Quantum XsOs is an extraordinary version of the classic tic-tac-toe!

You need to collect 4-in-a-row to win. First, the players put 2 pieces in turn, and then the measurement takes place - only one of the two pieces is saved. Thus, there is always the possibility of winning or losing!

- 4 types of playing fields - less is more difficult
- 3 opponents (Steve, Maria and Bill) with different strategies - beat everyone!
- Daily games, achievements and detailed statistics
- Night mode (visual themes are planned)
- Ability to play with a friend on one device

Just try it!
