i am smaart app for iPhone and iPad

With

- arithmetic equalities, and
- wall constraints

the 15-puzzle got upgraded to "i am smaart", a game for the brain.



Besides, you will not miss the classic features like number sequences (in decimal, hex and Roman notation) or letter sequences (in 3 alphabets: Latin, Greek and Cyrillic).

And you will also have dynamically generated images which will never repeat: with circles, with triangles or with rectangles, filled or outlined.

All in 3x3, 4x3, 6x2, 5x3, 4x4, 6x3, 5x4, 6x4, 6x5, 6x6, 7x6 and 8x6 boards.


Happy unpuzzling, everyone! :)



=Technical note=

The game uses a variable display refresh rate: from maximum when needed to zero, in order to save battery power. It preserves the experience and extends the autonomy.
