Random stack
Currently the wording "random stack" is slightly misleading - not all stacks get the same chance of being selected.
The game code chooses a stack by giving the top stack a 50% chance of being selected, and then halving the chances after that until you are out of stacks.
| Stack # | Chance of selection |
|---|---|
| 1 (aka top) | 50% |
| 2 | 25% |
| 3 | 12.5% |
| 4 | 6.25% |
| 5 | 3.12% |
| 6 | 1.56% |
| 7 | 0.78% |
| 8 | 0.39% |
| 9 | 0.19% |
| 10 | 0.01% |
