Crypto Casino Originals Odds: Your Chances in Crash, Dice, Limbo, Mines and Plinko

Crypto casino originals such as crash, dice, limbo, mines and plinko are best known for a 1% house edge, which means a 99% RTP. The target you pick, the number of mines or the plinko risk level changes how often you win and how big the swings are. At most casinos, it does not change what each bet costs you over time.

Not every original pays 99%, though. When we checked what five crypto casinos publish for their own games in October 2026, RTPs ran from 96% to 100%, so a crash bet can cost four times as much at one casino as at another.

Every odds figure in this guide is worked out from the game’s own formula and checked by simulation, and every RTP comes from the casino’s own pages or our checks in the game. VIP-Grinders has calculated odds and expected value for poker players since 2013, and the same maths decides every crash round and plinko drop.

This guide covers:

What Are Crypto Casino Originals?

Crypto casino originals are simple, fast games that a casino runs under its own brand, such as Shuffle Originals or BC Originals. Most are provably fair, which lets you check each result against the seeds behind it, and most settle a bet in a second or two.

Each casino sets its own payouts, so the same game can return a different amount from one site to the next.

The Games That Count as Originals

These are the five most common originals, and the ones this guide works through:

Many casinos add keno, wheel and HiLo to the list. The maths works the same way, since every original builds its edge into the payout.

Originals vs Provider Crash Games

Some crash games in a casino lobby are not originals at all. Aviator, made by the studio Spribe, runs at a 97% RTP, which is a 3% house edge.

Crash originals at Shuffle and BC.Game run at 99%, and Duel’s crash pays back 100% within its daily Zero Edge allowance. The cash out works the same way in all of them. The edge is the only real difference:

Do All Originals Pay 99%? What Each Casino Publishes

No. Across the five crypto casinos we checked in October 2026, RTP on originals ranged from 96% to 100%, and some casinos set a different edge for each game. We checked all five BC.Game games, Rainbet’s mines and Duel’s mines and plinko in the game itself, while the other figures come from each casino’s own game pages.

A 96% original costs four times as much per bet as a 99% one: $40 for every $1,000 you wager, against $10.

Where the 1% Edge Holds

Shuffle publishes a 1% house edge on its crash, dice, limbo and mines, and “around 1%” on plinko. Its crash page adds that the figure “holds whatever cash out target you choose”.

BC.Game’s crash also runs at 99%: with auto cash out set to 2x, the game shows a 49.5% chance, which is exactly the price of a 1% edge.

Rainbet lists 99% on its dice and limbo, and up to 99% on plinko. The 1% edge is common, but each casino sets it game by game.

Originals That Pay Less Than 99%

These are the games where our checks or the casino’s own pages show a bigger edge:

Several review sites still list BC.Game’s dice at 99%, but the game pays 1.96x at 50%. Only its crash runs at 99%, half the cost per bet of the same 2x target in limbo.

Zero Edge Offers and Their Limits

Duel runs its originals with no house edge up to a daily limit. The Zero Edge panel in its mines and plinko games sets out the terms:

What our checks in the game found:

A 100% RTP means the game costs nothing over time, but your results still swing from round to round.

BC.Game announced its own Zero Edge programme in January 2026, which pays the house edge back in BC tokens to VIP 5 players and above, up to a daily cap. Because it is paid back in tokens and not through the payouts, its dice, limbo, mines and plinko still show 98% in the game.

How to Check an Original’s Edge Before You Bet

RTP is the payout multiplied by the chance of getting it, as our guide on how RTP is calculated shows. That means you can work out any original’s edge from the game screen, without placing a bet:

This is the check that caught BC.Game’s dice at 98%. A 50% chance paying 1.96x returns 98 cents for every dollar over time:

House edge is 100% minus the RTP. When a casino does not print it, the payout on screen tells you.

Originals Odds Calculator

Pick crash or limbo, dice, mines or plinko, then enter the house edge your casino shows. The calculator works out your exact chance of winning, the payout, how often a session finishes ahead and what the edge costs, using the same formulas as the odds tables in the sections below.

How to Read the Calculator

What each result shows:

Try a 1.1x target and then a 10x target at the same 1% edge. The average loss on 1,000 bets of $1 stays at $10, while your chance of finishing ahead rises from 15.8% to 43.1%.

Where the House Edge Sits in Each Original

Most originals turn a random number into a result, then pay you slightly less than the fair price for that result. The gap between the two is the house edge, and each game puts it in a different place.

The random number comes from a provably fair process:

Our guide to checking a provably fair bet covers how to recheck each result. This is how each game prices the result once the number is drawn:

Crash and Limbo: 99 Divided by Your Target

At a 1% edge, your chance of reaching any target is 99 divided by the target, as a percentage. BC.Game publishes the crash formula that does this, and it shows how small the change from a fair game is:

Limbo prices its targets the same way, and Shuffle’s published limbo code sets the RTP at 0.99.

Dice: 99 Divided by Your Win Chance

In dice you pick the win chance, and the casino sets the payout. At a 1% edge the payout is 99 divided by your win chance, and at a 2% edge, as on BC.Game, it is 98 divided by it:

The edge takes the same share of every payout. No win chance is better value than another.

Mines and Plinko: Built Into the Payout Table

In mines and plinko the board fixes the odds. The casino puts its edge into the multipliers it prints:

BC.Game’s three plinko risk levels and Duel’s three boards all return about the same, and Shuffle states that its mines edge holds on every configuration. So the setting usually changes the spread of the payouts while the edge stays put.

Crash Odds: Your Chance of Hitting Each Multiplier

Crash gambling odds follow one rule: at a 1% edge, the chance that a round reaches your target is 99% divided by the target. A 2x target hits 49.5% of the time, a 10x target 9.9%, and a 100x target just under once in every 100 rounds.

Crash Multiplier Odds Table

These are the exact odds at a 1% edge, which is what Shuffle and BC.Game crash run at. The last column shows how many rounds it takes before you have even a coin flip’s chance of seeing that multiplier once:

Over 100 rounds, a 100x target hits at least once 63% of the time, but a 1,000x target only 9.4% of the time. On a game with a 2% edge, use 98 instead of 99: a 2x target then hits 49% of the time.

How Often Crash Ends at 1.00x

Some rounds crash before any cash out is possible. BC.Game’s published formula shows exactly how often:

These instant crashes are not an extra charge on top of the edge. They are already part of the 99 divided by target maths, so a 2x target still returns 99% over time.

Why Your Cashout Target Does Not Change the Edge

Your return on any target is the chance of hitting it multiplied by the payout, and in crash the two always cancel out to the same figure:

Cashing out by hand works the same way, because the crash point is fixed before the round starts. A low target wins often and pays little, while a high one rarely wins and pays a lot.

Limbo and Dice Odds: Win Chance, Payout and Edge

Limbo and dice look different, but they are priced the same way. At a 1% edge, a 2x payout always comes with a 49.5% chance, whether you set it as a limbo target or a dice roll.

Limbo: Crash Odds Without the Wait

Limbo draws one multiplier the moment you bet, and you win if it reaches your target. The odds match the crash table above: a 10x target wins 9.9% of the time at a 1% edge and 9.8% at BC.Game’s 2%.

What differs is how the game runs:

Dice and Limbo Are the Same Bet

Every limbo target has a dice setting with the same chance and the same payout. At a 1% edge they line up like this:

So the choice between dice and limbo comes down to the screen you prefer and the edge your casino sets on each game. At BC.Game both run at 2%, while at Shuffle and Rainbet both run at 1%.

Over or Under Makes No Difference

Neither of these changes your odds:

Our test of the Martingale system on crypto dice shows what happens when players raise their stake after a loss instead.

Mines Odds: Your Chance of Clearing Each Tile

On the standard 25 tile grid, your odds in mines depend on two numbers: how many mines are on the board and how many tiles you open. With 3 mines, you clear 5 tiles 49.57% of the time, and a 1% edge pays 2.00x for it.

Mines Probability Chart

Your chance of clearing each number of tiles on a 25 tile grid:

To turn any chance into a payout at a 1% edge, divide 99 by it. With 10 mines, clearing 8 tiles happens about once in 168 rounds, which is why it pays 166x.

More Mines Pay More at the Same Edge

Adding mines raises the payout per tile because each tile is riskier, but the price stays at the same edge. Settings with the same chance of success pay the same:

Rainbet also offers grids of 36, 49 and 64 tiles, and the same rule applies. With 3 mines on 64 tiles, the first tile is safe 95.3% of the time, so it pays just over 1x.

Is There a Best Time to Cash Out in Mines?

No. At a 1% edge, every multiplier in a round is 99 divided by your chance of getting that far, so the round costs 1% of your stake whether you open one tile or ten.

This is the ladder for 3 mines at a 1% edge and at the edges we found at BC.Game and Rainbet:

The cost comes from the number of rounds you play: the edge is charged once per round, so ten rounds of one tile cost ten times as much as one round of ten tiles.

The tiles you pick make no difference either. On a provably fair board the seeds place every mine before your first click, and each tile is equally likely to hide one.

Plinko Odds: How Often the Ball Hits Each Slot

Plinko odds, the probability of the ball landing in each slot, come from the number of rows alone. At each peg the ball has an even chance of going left or right, so the slot it lands in follows a fixed pattern: with 16 rows, the centre slot catches 19.6% of drops and each edge slot just 1 in 65,536.

Plinko Odds by Number of Rows

More rows spread the ball across more slots, which makes the edges rarer and lets the casino put bigger multipliers there:

Each casino then decides the multiplier it prints on each slot.

What the Risk Level Changes

BC.Game’s 16 row boards show what each risk level does. The chance of every slot stays the same, and only the multipliers move:

All three boards return about 98%. Regular pays under 1x on 19.6% of drops, while High and Nightmare pay under 1x on 79% of them.

The share of drops that pay more than your bet falls from 45.5% on Regular to 21.0% on High and 7.7% on Nightmare.

How Rare the Plinko Max Multiplier Is

On 16 rows, the ball lands in one of the two edge slots once in 32,768 drops. That makes the top multiplier something most players never see:

On Nightmare, the two 10,000x slots supply 31% of everything the board pays back. Leave them out and the rest of the board returns about 67.6%, so most sessions run well below the 98% figure.

Same Edge, Very Different Sessions

We calculated 1,000 bets of $1 at five limbo targets, all at the same 1% edge. Every row loses $10 on average, but the results spread very differently:

Every figure comes from exact probability maths, and we checked each row with a simulation of 200,000 sessions. The same results apply to crash with auto cash out at the same targets.

Low Targets: Frequent Wins, Steady Losses

A 1.1x target wins 9 bets in 10, which makes it feel safe. Over 1,000 bets, though, it finishes ahead in only 15.8% of sessions.

The swings are tiny: 8 sessions in 10 end between $23 down and $3 up. With 1,000 small bets, almost every session lands close to the $10 average loss.

High Targets: Long Droughts, Rare Spikes

At high targets, the same $10 average comes from long losing runs and a few big wins. Most bets lose, and one hit can turn a whole session around:

What a Higher Edge Adds Up To

The edge decides the average cost, and that cost grows with every dollar you wager. This is what each edge from our casino checks costs over $1,000:

A bigger edge also pulls every session down. At 2% instead of 1%, a 1.1x target finishes ahead in just 2.7% of sessions, against 15.8%, and a 2x target in 25.3%, against 36.4%.

Speed matters too, because autobet can place 1,000 bets in a single short session. Our guide to what the house edge costs you per hour works through that side of the maths.

What Changes Your Odds in Originals and What Does Not

Most settings in an original change how a session feels, and mainly the casino you choose changes what each bet costs. This table sums up every setting covered in this guide:

In the settings we checked, the edge stayed the same. The exception to watch is Rainbet’s plinko, which it lists as up to 99%, so one setting there can pay less than another.

The Only Two Things That Change Your Cost

Your average loss in any original comes down to two numbers multiplied together:

Picking a casino with a lower edge and wagering less are the only ways to lose less over time.
