Claim the grid. Meet only at the corners. Four colors share a 20 x 20 board. Each holds the same 21 tiles, from a single square to every five-square shape. The one rule: your tiles may touch each other only corner to corner, never along a side. Other colors can press right against you, so every tile you place opens room for you and closes it for someone else. PLAY THE FIELD Take Ember against three on-device rivals. Easy is relaxed, Normal plays solid tiles, and Hard reads territory, keeps its own corners alive and cuts off yours. DAILY QUARRY A new board every day with stones nobody can cover, the same for everyone, against three Hard rivals. Keep your streak going. QUARRY BOARDS Add symmetric stones to any Field match for a different game every time. HOTSEAT Pass one phone between 2 to 4 players. With two players each controls two colors. Undo is one tap away. MADE FOR FINGERS Drag a tile onto the board and a live ghost shows green where it fits and red where it does not. Tap to turn it, flip it, or jump straight to the next legal spot. Hints and undo are there when you want them. LEARN IN A MINUTE A short hands-on tutorial teaches the corner rule by playing it.
