Tower in short
Tower is a nine-floor climb. Each floor has three lanes and one of them hides a mine. Pick one, and if it is safe the multiplier rises and you can climb to the next floor. You can cash out at any point; hit a mine and the whole stake is gone.
The mechanic is close to Mines, but one thing is fundamentally different and worth catching: in Tower the house edge applies on every floor separately. Mines takes its percentage once for the whole round; Tower takes it nine times.
That makes Tower the game in the fast-games family where the advertised number and the real number diverge the most. Both are below.
How a round works
- Bet. You stake before the first floor.
- Pick a lane. One of three lanes is a mine — the safe chance is 2 in 3.
- Climb or cash out. A safe pick multiplies the running total by 1.485 and opens the next floor.
- The top. The ninth floor ends the round at the maximum multiplier.

Why the last column falls
Each floor on its own is priced correctly: the safe lane is two in three and the multiplier is 1.485, which gives 0.667 × 1.485 = 0.99. One percent to the house, exactly as in crash or dice.
But you are not making one decision. You are making them in sequence, and each further decision takes its one percent again, off an already-reduced amount. Nine floors means 0.99 to the ninth power:
0.99⁹ = 0.9135, or 91.4%.
That is almost nine percent of house edge — more than a typical slot and three times roulette. The game is not lying: each step really is 99%. But the return on a full climb is a different number entirely, and it is written down nowhere.
Which floor to stop at
| How much risk | Floor | Multiplier | How often it works |
|---|---|---|---|
| Little | 1–2 | 1.49–2.21× | Close to half of rounds |
| Moderate | 3–4 | 3.27–4.86× | Every third to fifth round |
| A lot | 6–7 | 10.72–15.93× | Every 11th to 17th round |
| All or nothing | 9 | 35.12× | Every 38th round |
If you set the target in advance and stick to it, the table shows exactly what it costs. The cheapest Tower is a short Tower.
Three things worth knowing
- Lane position is irrelevant. The mine is placed at random on each floor and the left, middle and right lanes are identical.
- Previous floors do not affect the next one. Each floor is a fresh 2-in-3 decision. Three correct picks in a row make the fourth neither more nor less likely (the gambler's fallacy).
- The same compounding applies in Hi-Lo and in any game where a win can be risked again — including the gamble feature in slots.
