Games like Dice, Limbo, and fixed-cashout Crash let you choose your own multiplier, which changes your hit rate and streak profile. This calculator does not remove the house edge. It helps you size an auto-bet progression, calculate the break-even increase-on-loss percentage, and see how many consecutive losses your balance can survive — plus how likely that bust streak actually is.
Important: a martingale progression does not change the expected value of your play. Over time, the house edge (typically 1% on Stake/BC.Game originals) ensures a mathematical loss. What this tool does is show you the risk profile of your specific progression settings — so you can see whether your bankroll is sized for the streaks that will inevitably come.

How to Use the Calculator
This tool simulates the “Auto Betting” panel found on most crypto casinos. Here is how to verify your progression settings before risking real crypto:
- Enter Balance & Base Bet: Input your total balance and your starting bet size (e.g., $0.01 or $1.00).
- Sync Multiplier & Chance:
- If you are playing Limbo/Crash, enter your target multiplier (e.g., 10.00x). The calculator adjusts win chance automatically using the formula
99 / Multiplier(1% house edge default). - If you are playing Dice, enter the win chance (e.g., 49.5%) and the multiplier adjusts.
- If you are playing Limbo/Crash, enter your target multiplier (e.g., 10.00x). The calculator adjusts win chance automatically using the formula
- Set “Increase on Loss”:
- For a standard 2x payout, this is 100% (classic Martingale doubling).
- For higher multipliers, you don’t need to double. Click “Auto: Break-Even” to find the minimum increase needed to recover all losses on the next win. Formula:
100 / (Multiplier − 1).
- Analyze Results:
- Safe Losses: How many consecutive losses your balance can survive.
- Bust Probability: The chance of hitting that many losses in a row (per attempt window).
- Progression Table: Exact bet size, cumulative risk, and profit-if-win for each step.

Real-World Examples: Auto-Bet Settings
Different multipliers require different progression math. Here are three scenarios players commonly analyze.
Example 1: The “Safe” 2x Dice Strategy
You play Dice with a 49.5% Win Chance (2.00x Payout), $1 base bet, 100% increase on loss (classic doubling), $500 balance.
- Safe Streak: 8 losses. You bust on loss #9 (cumulative risk: $511).
- Bust Streak Probability: (0.505)9 ≈ 0.21% per window — roughly 1 in 468.
- Insight: 0.21% sounds safe, but over 1,000+ rounds this streak becomes likely. The calculator helps you see that $500 is barely enough for a $1 base bet at 2x — you need $1,000+ for meaningful safety margin.
Example 2: The “Moon” Limbo Strategy (10x)
You hunt a 10.00x Payout on Limbo with $0.10 base bet and $500 balance.
- Naïve approach (100% increase): Bust after only 9 losses — terrible.
- Optimized (Auto Break-Even = 11.11%): Safe streak expands to 60 losses.
- Bust Streak Probability: (0.901)61 ≈ 0.13% per window.
- Insight: By increasing only ~11% per loss instead of doubling, you survive 60 rounds instead of 9. The break-even button does this math instantly.
Example 3: Why Wrong Increase % Destroys You
Comparing two settings for the same 3x Dice game ($500 balance, $1 base bet):
- 100% increase (doubling): Safe streak = 8, bust probability per window = 1.5%.
- 50% increase (Auto Break-Even for 3x): Safe streak = 16, bust probability per window = 0.004%.
- Insight: The break-even increase for 3x is 50%, not 100%. Using 100% wastes bankroll on oversized bets, halving your survivable streak.
Frequently Asked Questions (FAQ)
How is the Win Chance calculated?
For crypto casino originals running on 99% RTP / 1% house edge (standard for Stake Dice, Limbo, BC.Game, etc.), the formula is 99 / Multiplier = Win Chance. A 2.00x multiplier has a 49.5% win chance, not 50%. Games with different RTP require adjusting the edge factor.
What is the “Break-Even” increase?
The minimum geometric increase per loss that recovers all previous losses and restores the original profit target on the next win. Formula: 100 / (Multiplier − 1). For 2x: 100%. For 3x: 50%. For 10x: 11.11%. Using a higher increase than break-even is unnecessary and wastes bankroll depth.
Does this work for Crash gambling?
Yes, if the game uses the same fixed-target multiplier model with 1% house edge. For 99% RTP originals such as Stake Dice, Limbo, and Stake Crash, the calculator is directly applicable. Games with different RTP or different crash mechanics need a different edge factor.
How likely is it that I actually bust?
The probability of a bust-triggering streak in any specific window is (1 − winChance)N+1, where N is your safe streak count. For 2x Dice with 8 safe losses, that is roughly 0.21% per window. But over hundreds or thousands of rounds, the cumulative probability of encountering at least one such streak is much higher — use the Streak Calculator to estimate that.
What if my casino has a different house edge (e.g., 2% or 3%)?
Change the edge factor accordingly: for 2% edge, use 98 / Multiplier; for 3%, use 97 / Multiplier. The default 1% (99/Multiplier) is standard for Stake, BC.Game, and most major crypto casino originals. A higher house edge means lower win chance at the same multiplier, which increases bust probability.
Should I reset to base bet after a win?
In a standard Martingale, yes — you reset to your original base bet after any win. The progression table assumes this: each “Profit if Win” value shows the net gain after recovering all accumulated losses. If you do not reset, you are running a different (and riskier) system.
