We create fun and engaging puzzle games
Happen Labs makes logic puzzles for iPhone and Android. Every board has exactly one answer, and you can always reason your way to it — no guessing, no dead ends.
They are free, they need no account, and they work with no connection at all. Play on a plane, on the metro, or anywhere else you end up waiting.
