what exactly causes a strike? sometimes i can not quite perfect a level and not get one, othertimes like the balancing one i might only be 1 off and i get a strike
It depends on the game. I added all the rules of different games to the description above (along with how the strikes are given).
Basically:
- Ancension: strike per unopened row
- Balancing: strike per diff (level number max)
- Scales: strike per diff in opponent ticks vs your ticks
- Descale: strike per unflipped card
