LineaLogic

A real logic game. Not another app stuffed with ads. Not a subscription that costs you more every month. Just an elegant puzzle where every challenge is solved by reasoning.

Every puzzle gives you a clue. Pick the right sticks — each one has a colour and a size — to satisfy every constraint at the same time. A large red stick counts as both “large” and “red”.

You get 7 progressive difficulty levels and 70+ deduction puzzles. Level 1 is completely free, so you can try before you buy. Zero ads, zero subscriptions, one lifetime purchase unlocks everything. No timer, no lives, no game over.

For fans of Sudoku, deduction riddles and calm brain-training games. Works offline, requires no account, and respects your time and money.
