ThinkGrid: Calm Logic Puzzles

ThinkGrid is a calm collection of logic puzzles for people who want to think,
not be sold to.

Eight hand-crafted puzzle types in one quiet app. No ads. Ever. No coins,
no timers counting down, no popups asking you to buy something at the exact
moment you got stuck. Just puzzles, and the slow pleasure of working one out.
