Rules and help

Clear every rune tile and return to the starting tile on your final move. Standing on the start initially does not use a hit. Returning to it too early makes the puzzle impossible to finish.

Tap a directly neighboring tile or swipe diagonally. On the isometric board, up-right corresponds to the grid direction up; down-right to right; down-left to down; and up-left to left.

Tiles need one, two or three hits. Entering a tile uses one hit. You can leave a tile after its last hit, but you cannot enter it again.

A current carries you one tile in the arrow's direction after you enter it. Both tiles use a hit. The move is blocked if its destination cannot be entered. A whirlpool takes you to its partner and uses a hit there too. If its partner is already cleared, it acts as an ordinary tile.

Clear all key runes first. You can then enter the sealed tiles.

Choose Restart to begin the level again. There is no undo control in the game view. Dead ends are reported immediately in the first five levels. You can enable the warning for later levels in Settings.

Complete a level on your first attempt for three stars, within three attempts for two, and later for one. You can replay solved levels. Your best star result is kept.
