Match two identical tiles joined by a path with at most two turns.
Every tile on the board has a twin somewhere else. Tap one, then tap its twin, and both disappear — but only if the two can be joined by a path that turns no more than twice. The path travels through empty space, never through another tile, and it is allowed to leave the board and come back around the outside.
That last part is what most new players miss. Two tiles in opposite corners can often be linked by going out through the edge and around, even though there is no visible route between them.
Three turns is never allowed, no matter how obvious the route looks. If a pair will not clear, count the corners.
Most versions of this game let you reach a position with tiles still on the board and no legal pair anywhere, and then leave you to work out that you are finished. This one checks after every single match. The moment no legal pair exists, the remaining tiles are shuffled automatically and you are told it happened.
So a board is always finishable. The only thing that runs out is your patience, not the puzzle.
Clear tiles from the outside inward. Edge tiles are the easiest to reach, and removing them opens paths for the tiles buried in the middle. Clearing the middle first feels productive and leaves you with a solid ring of tiles that can only be linked by going the long way around.
When you spot three or four of the same symbol, think before tapping. Which pair you clear changes which paths open next, and one of the two choices is usually much better than the other.
The hint button highlights one legal pair. It always finds one if a pair exists — it is not guessing. Shuffling is unlimited and free, but each shuffle is counted and shown at the end, so a clean solve is one with none.
