Computational Puzzle Apps

Logically Yours designs and implements computational apps for fun.

Enjoy a minimalistic clear graphical design, tap or slide tiles with or without animation. Enjoy some fun move sounds as: thud, click, wave, ... beeps at move specific frequencies and even female and male spoken voice of each specific move. Compete between friends or on global leaderboards for the fastest times and the fewest moves. Use hints from a layer by layer solver for humans or enjoy watching a super-human play the game in the minimal possible amount of moves.
