Litty Tech NG is an independent studio making offline logic puzzles and everyday utility apps for Android. Every puzzle we ship has exactly one true solution, reachable by pure deduction — no guessing, no filler.
Every board below is generated and then independently re-solved before it ships — confirming a unique solution exists and that no guessing is required to find it.
Fill cells from row and column clues alone, and watch a picture emerge.
Picture LogicMatch every tree to a tent beside it, without any two tents touching.
Grid LogicA Latin square where black and white dots — and their absence — decide every cell.
Number LogicDraw a diagonal in every cell so corner counts add up — and no loop ever closes.
Path LogicFill irregular regions with 1 to their size, with no repeat touching even diagonally.
Region LogicA growing catalog of offline puzzle games and everyday tool apps.
Full catalog on Play StoreLitty Tech NG is an independent Android developer based in Nigeria. We build offline-first apps — logic puzzle games and practical utility tools — designed to work fully without a network connection and without collecting data we don't need.
Every puzzle we publish is machine-verified before release: generated, then independently re-solved to confirm a single correct answer exists and that it's reachable through logical deduction alone, not trial and error.
We keep our catalog small enough to stand behind personally, and we're always working on the next board.
We read everything that comes in — puzzle feedback included.
