About Check3
Put three check marks in every row and every column. Check marks may not be placed next to or above each other. Tip: put a cross on the positions that may not contain a check mark. Check3 turns idle minutes into satisfying "aha" moments. Press Play and work the board one move at a time. It's a straightforward puzzle game that gets out of your way and lets you play. Pick it up for a short break or settle in for a while — it runs well on phone, tablet, and desktop alike.
A couple of things help once you get going: Work from the corners and edges inward — they usually have the fewest possible solutions. If the game has a hint button, save it for when you are genuinely blocked, not just slow.
You can play Check3 free online at Glaze Games — it loads in seconds, works on phone and desktop, and never asks you to sign up.
