Fillshape

Fillshape is an engaging puzzle game, the first in a new series of games featuring a cheerful traveller. Accompanied by the main character, you set off on a journey where you’ll have to work out tough logic conundrums, paint shapes, and piece together some kind of jigsaw puzzles; where a crafty riddle will be a typical quandary to encounter, where you’ll find yourself in puzzlement thinking of a way out of a mysterious ice boulder maze and have to find the best solution and move combinations to complete each new quest. This game will immerse you into a world of challenging solutions where there's no room for confusion.
The game rules are simple: you have to paint all the square spaces green by moving a counter over them. You can’t move backwards. By sliding the counter onto a space you change its colour. When you move the counter over the same space another time, it changes colour again. The colours change in the following sequence: red - blue - green.
The game features Practice Mode and hints, and you can cancel your previous move and restart a level.
Now apart from five seasons, i.e. 150 levels in total, there are weekly tournaments and quick games (NB: Season 5 is only available in Premium Version).
That’s Fillshape for you, where you pump up your brain in engaging gameplay - each and every moment of it.
