@laprofe Level 920 is the last level in AlphaBetty Saga and no more levels are planned at this moment.
It's not either decided when or if new levels will come again in the game.
I can recommend to either go back and replay old levels and try to beat your previous scores.
The other alternative is to start over again from level 1 and play the game again. You can either start to play on a brand new account or just let @Crazy Cat Lad know and he will reset your game back to level 1 on your existing account.
