DIFFICULTY LAYOUTS
| Difficulty | Good Columns | Bad Columns | Clear Chance Per Row | Bust Chance Per Row |
|---|---|---|---|---|
| Easy | 3 | 1 | 75.00% | 25.00% |
| Medium | 2 | 1 | 66.67% | 33.33% |
| Hard | 1 | 1 | 50.00% | 50.00% |
| Expert | 1 | 2 | 33.33% | 66.67% |
| Master | 1 | 3 | 25.00% | 75.00% |
ROUND FLOW
- A safe pick moves you up one row.
- After every safe row, you can cash out or keep climbing.
- One bad pick ends the round immediately.
- The tower always ends after row 9, so row 9 is the maximum possible cashout.
PAYOUT LOGIC
- Easier modes clear more often, but each extra row adds less multiplier.
- Harder modes bust more often, but surviving one more row increases payout much faster.
- The real strategic choice is always the same: lock the current multiplier now, or accept one more row of bust risk for a larger cashout.
OVERVIEW
Waifu Tower uses one fixed tower length and one fixed house edge. The only thing that changes with difficulty is the row survival probability.
PARAMETERS
| Symbol | Meaning |
|---|---|
p(D) | probability of clearing one row at difficulty D |
n | number of rows you plan to clear, from 1 to 9 |
M(D,n) | cashout multiplier for difficulty D after n clears |
ROW SURVIVAL
Because each row uses the same layout inside a chosen difficulty, the chance to survive n rows is:
FIRST-STEP PRICING
The 2% house edge is charged on the first step:
LATER ROWS
After the first row, each extra row is priced at 0% additional edge:
Equivalently, every time you keep climbing, your current multiplier is multiplied by 1 / p(D).
DIFFICULTY SNAPSHOT
| Difficulty | p(D) | First-row multiplier | 9-row multiplier |
|---|---|---|---|
| Easy | 0.75 | 1.3067x | 13.0519x |
