How do I calculate a dice multiplier?

Divide 100 minus the house edge by the win chance. With a 1% edge and a 25% chance, the multiplier is 99 divided by 25, which is 3.96.

How do I find the house edge of a dice game?

Multiply the win chance, as a fraction, by the multiplier and subtract the result from 1. A 50% chance paying 1.98 gives 0.5 times 1.98, which is 0.99, so the edge is 1%.

What win chance gives a 2x payout?

At a 1% edge, 49.5%. At a 2% edge, 49%. That is why a 2x bet on crypto dice never wins exactly half the time.

What are the odds of losing ten times in a row?

At a 49.5% win chance, about 0.108%, or 1 in 927. At a 90% chance, it is one in ten billion. The lower your win chance, the longer and more frequent your losing streaks.

Does the target change the house edge?

Not on a correctly built dice game. Every target carries the same edge; only the size and frequency of wins change.

Dice odds calculator: every win chance, multiplier and target

One formula links the win chance, the multiplier and the house edge on every crypto dice game. Here it is worked out for 26 targets, with the roll under and roll over lines and the odds of losing five rolls in a row.

Every crypto dice game runs on the same arithmetic, so one dice odds calculator covers all of them. Below is the formula, a full table for the targets people actually use, and how to read any dice screen in reverse to find the edge it charges.

The formula

Three numbers describe any dice bet: the win chance (in %), the multiplier (what a win pays, stake included) and the house edge (in %). They are linked by:

multiplier = (100 − house edge) ÷ win chance

and, rearranged,

house edge = 100 − win chance × multiplier

Two quick checks:

25% chance, 1% edge: 99 ÷ 25 = 3.96×.
A game shows 50% at 1.96×: 100 − 50 × 1.96 = 2% edge.

The dice odds table

Roll under uses the target as shown; roll over uses 100 minus the chance. The last column is the chance of losing five rolls in a row at that win chance, the number most players underestimate.

Win chance	Multiplier (1% edge)	Multiplier (2% edge)	Roll under	Roll over	5 losses in a row
0.01%	9,900.00×	9,800.00×	0.01	99.99	99.95%
0.1%	990.00×	980.00×	0.10	99.90	99.5%
0.5%	198.00×	196.00×	0.50	99.50	97.5%
1%	99.00×	98.00×	1.00	99.00	95.1%
2%	49.50×	49.00×	2.00	98.00	90.4%

55%	1.8000×	1.7818×	55.00	45.00	1.8%
60%	1.6500×	1.6333×	60.00	40.00	1.0%
66%	1.5000×	1.4848×	66.00	34.00	0.454%
70%	1.4143×	1.4000×	70.00	30.00	0.243%
75%	1.3200×	1.3067×	75.00	25.00	0.098%
80%	1.2375×	1.2250×	80.00	20.00	0.032%
85%	1.1647×	1.1529×	85.00	15.00	0.008%
90%	1.1000×	1.0889×	90.00	10.00	0.001%
95%	1.0421×	1.0316×	95.00	5.00	under 0.001%
98%	1.0102×	1.0000×	98.00	2.00	under 0.001%

Two things stand out. First, the difference between a 1% and a 2% edge looks tiny per row and doubles the long-run cost of play. Second, at low win chances a string of five losses is not a bad run; it is the normal case.

Reading a dice screen in reverse

You rarely need to trust a game's own claim about its edge. Take any target from the screen and multiply the win chance by the multiplier:

Game shows	Chance × multiplier	Edge
50% → 1.98×	99.0	1%
50% → 1.96×	98.0	2%
33% → 2.97×	98.0	2%
10% → 9.90×	99.0	1%

If the result is 99, the edge is 1%. If it is 98, the edge is 2%. Anything lower means you are paying more for the same game. The in-house dice on the sites in our crypto dice games ranking typically show 99, but check the game you play, because settings can differ by site and by product.

Expected cost of a session

The edge applies to every unit you wager, so the expected cost of a session is simply:

expected cost = total wagered × house edge

Stake per roll	Rolls	Total wagered	Expected cost at 1%	at 2%
0.10 USDT	1,000	100 USDT	1 USDT	2 USDT
1 USDT	500	500 USDT	5 USDT	10 USDT
5 USDT	300	1,500 USDT	15 USDT	30 USDT
20 USDT	200	4,000 USDT	40 USDT	80 USDT

This is the average. Any single session can end far above or below it; the table tells you what the game charges you for the ride, not where the ride ends.

Losing streaks at common targets

Players pick targets by how often they win. They should also look at how often they lose several times in a row, because that is what empties a balance under a doubling system.

Win chance	5 losses in a row	10 losses in a row	1 in … for 10 losses
90%	0.001%	0.00000001%	10,000,000,000
66%	0.454%	0.00206%	about 48,500
49.5%	3.3%	0.108%	about 927
33%	13.5%	1.82%	about 55
10%	59.0%	34.9%	about 3

Bar chart of the chance of losing ten dice rolls in a row at different win chances — On a log scale: at a 10% win chance a ten-loss run happens about a third of the time; at 49.5% about once in 927 starts; at 90% about once in ten billion.

At 49.5%, a ten-loss streak comes about once every 927 starting points. Over a thousand rolls, the chance of meeting at least one is about 2 in 5; over three thousand rolls, about 4 in 5. That single fact is the reason the crypto dice strategy page spends so long on Martingale.

Where to use this

Before a session, pick the win chance whose losing streaks you are comfortable with, not just the payout you like.
Before a bonus, work out how much you will wager to clear it and multiply by the edge to see the expected cost.
Before trusting a new site, reverse-check the multiplier at two targets. If both give 99, the edge is 1%.

The mechanics behind every number here are explained in how crypto dice works, and the way to prove individual rolls were honest is in provably fair dice.

Numbers do not make it safe

A calculator makes dice look controllable, and in one sense it is: you know the price of every bet. What it cannot do is make a loss affordable. Decide what you will wager before you start and stop when you get there. Gambling is for adults over 18; free, confidential help is available from Gamblers Anonymous and GamCare.
