Just to keep it short and simple - a new update to the game just hit the stores - you can get it on all platforms.
Changes in 2.1.5:
1. Adventure Mode - new game mode in which you can extend the available memory the way you like - a great challenge for veterans!
2. Assign 24 new shapes, available in all game modes!
3. UI improvements:- un-optimal app assignment has unique animation- assigning slots has richer animation- hidden game stats (they will appear on game over)
4. Balance changes to all game modes - probabilities and generation of shapes has been modified. This results in slightly better gameplay.
