Stack.bet’s 0% base house edge describes the configured relationship between a tile’s base survival probability and its growth multiplier. It does not mean a round is safe, that every player has the same outcome, or that losses cannot occur.
What the 0% base house edge claim means
The active Stack.bet rules set the base edge value for every published risk-table row to zero. The game then calculates the base bust chance from that tile’s growth factor. In other words, the displayed base probability and multiplier are calibrated together rather than having an additional percentage removed as a base house margin.
This is a statement about the configured base math. It is not a prediction for one round, one player, or one session. A player can still bust on the first tile, lose a full stake, or reach a multiplier and then lose it by continuing instead of cashing out.
The base calculation
Each tile has a growth factor. At a zero base edge, the corresponding base survival probability is the reciprocal of that factor. The base bust chance is what remains.
Base survival probability = 1 ÷ tile growth factor
Base bust chance = 1 − base survival probability
Base expected factor = survival probability × growth factor ≈ 1.00
For level 1, the current growth factor is 1.05. The base survival probability is therefore approximately 95.2381%, leaving a base bust chance of approximately 4.7619%. The public risk table rounds that value to 4.8%.
The ≈ symbol matters: public display values are rounded, and this step-level explanation is before placement-related effects. It is not a guarantee that a player will receive their stake back.
How to read the risk table
Higher levels pair a larger cumulative multiplier with a higher chance that the next tile busts. The base edge stays at 0%, but the likelihood of surviving the next step does not stay constant.
| Level | Next-tile bust chance | Cumulative multiplier | Base house edge |
|---|---|---|---|
| L1 | 4.8% | 1.05x | 0% |
| L10 | 15.9% | 2.3x | 0% |
| L20 | 45% | 112.38x | 0% |
| L30 | 70.5% | 1171935.85x | 0% |
The multiplier is cumulative after the named level. It should always be read alongside the next-tile bust chance, never in isolation. You can review the live public table in the How it works section before placing a bet.
Where placement quality changes the round
The base risk table is only one part of Stack.bet. Every accepted tap is evaluated for placement quality. The current rules distinguish Perfect, Great, Good, Okay, and Sloppy placements. A perfect placement adds no placement pressure; less precise placements add progressively more pressure to the stack. A missed placement ends the round.
That is why “0% base house edge” and “skill matters” can both be true. The base probability and multiplier do not include a house margin, while the quality of the player’s placement can make the next step less forgiving.
What 0% does not mean
It does not mean there is no chance or variance.
It does not mean every round, player, or session will break even.
It does not mean a high multiplier is likely to be reached.
It does not remove the consequences of an imperfect or missed placement.
It does not make real-money play risk-free or guarantee a profit.

Methodology and change control
This article was reviewed on against Stack.bet’s live public risk table, the public base-edge and grade configuration, and the matching backend and game-service calculation source. Percentages shown in the table are rounded for public display.
If the active rules or public risk table change materially, this article’s last-reviewed date and examples must be updated with them.
