Quick tips

• See shapes, not tiles. Group the lit tiles into a shape (an L, a diagonal, a square). One shape is easier to remember than six separate tiles.
• Split the board. On larger grids, remember the top half and the bottom half as two small patterns.
• Tap in a fixed order. Order does not matter for the game, but always tapping top to bottom keeps you from skipping a tile.
• Don't rush the first tap. When the tiles go dark you have all the time you need. Rebuild the picture in your head, then tap.
• Learn from misses. After a wrong tap the pattern is shown: note what you forgot (usually a corner or an isolated tile).
