Just Number Blocks

Over 1000 hand-curated Suguru puzzles, in a quiet style. Fully offline, no ads, no timers.

Just Number Blocks is a quiet take on Suguru — a logic puzzle of regions and numbers. The board is divided into regions of irregular shapes (size 1 to 6). Fill each region with the numbers 1 to N where N is the region's size, with one extra rule: no two cells with the same number may touch, including diagonally.

Three small rules govern the whole game:

1. Tap a cell to select it, then tap a number on the pad. The number must fit the region (1 to region size).
2. Each region holds 1, 2, 3 … up to its size, each appearing once.
3. No two cells with the same number may touch — including diagonally.

Simple rules, plenty of room to think.
