How it works
Crypto dice rolls a number from 0 to 100 and you win if it lands under your target, so the target is your win chance. The multiplier follows from it: (100 − house edge) ÷ target. Pick 50 and you get roughly 1.98×; pick 2 and you get roughly 49.5×.
Because the multiplier is derived from the chance, every target carries the same expected value — the house edge, usually 1%. A low target is not better value with more risk, it is the same edge with a much longer tail, which is why losing streaks at high multipliers run far longer than players expect.

How the Dice Calculator works
Crypto dice is the simplest bet in the casino: roll a number from 0 to 100 and win if it lands under your target. This free dice calculator converts between the roll-under target and the multiplier, and shows the win chance, expected value and the real odds of a losing streak.
Target, multiplier and house edge
Your target is your win chance: set it to 50 and you win 50% of rolls, set it to 2 and you win 2% of rolls. The multiplier is derived from it as (100 − house edge) ÷ target, so a 1% edge gives 1.98× at a target of 50 and 49.5× at a target of 2. The calculator works in both directions — set the target and read the multiplier, or ask for a multiplier and get the target you need.
Because the multiplier and the chance are two views of the same number, the expected value never moves: it is the house edge, typically 1% of your stake per roll. That is unusually low for a casino game, but it is charged on every single roll, and dice rolls fast.
Streaks are longer than they feel
At a 2% win chance you miss 98% of rolls, and a hundred misses in a row is a perfectly ordinary occurrence. This is where dice players get hurt: the low edge invites big sessions and the long tail invites martingale-style doubling, which turns a slow 1% bleed into a fast bankroll-ending one.
The streak table on this page gives the exact probability of n losses in a row for your settings. Compare it against your bankroll before you decide a progression is safe, and see the risk-of-ruin calculator for what a −1% edge does over thousands of rolls.
FAQ
How is the dice multiplier calculated?expand_more
Multiplier = (100 − house edge) ÷ your roll-under target. With a 1% edge and a target of 50, that is 99 ÷ 50 = 1.98×.
What is the house edge on crypto dice?expand_more
Usually 1%, which is among the lowest in any casino game. It applies identically to every target, so no setting is better value than another.
Can you beat dice with a betting system?expand_more
No. Every roll is independent and every target carries the same 1% edge, so no staking pattern can turn it positive. Progressions only change how quickly you reach a big loss.
