1Pick a direction. Every gem on the board slides that way at once, until it hits a wall, the edge, or another gem.

2Match the color. Land a gem on its matching dashed target and it locks in place forever — now it's part of the puzzle too.

3Think in chains. A locked gem becomes a wall for the others. Use that to redirect gems you haven't solved yet.

4Clear every target to win. Fewer moves and zero hints earns you 3 stars.

5Stuck? Tap the lightbulb for a hint — it shows the next best direction to shift.
