Logic puzzles for your phone
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 work with no signal, and they do not need an account. A plane, a subway, a waiting room: all fine.
