Pull, release, CLACK! 150 levels, a new Daily Clack every day, and weekly events with exclusive ball finishes. Can you clear the board in the fewest moves?
Pull. Release. CLACK!
Clack! is a calm, satisfying puzzle inspired by the Newton's cradle. Drag the end ball outward and let go – the hit travels down the rail, and the ball at the far end flies into the cup. Pull two or three balls, and that many fly off the other end.
HOW TO PLAY
• Pull from either end of a rail and let go.
• A ball that matches the cup drops in. Each cup takes three balls, then the next cup moves up.
• A ball of the wrong color waits in the tray. Five in the tray and the level is lost.
• Clear the board in as few moves as you can to earn all three stars.
150 LEVELS, 3 CHAPTERS
Play through The Office, The Library and The Laboratory – each with its own setting and music.
New mechanics keep arriving as you go:
• Balls shared by two rails, and rails that cross
• Heavy brass balls and soft rubber balls
• Hidden "?" balls and capped rail ends
• Frozen balls, glass that shatters, and chrome balls that fit any cup
• Chained rails with gold-key balls
• Color-flipping balls, chutes, magnet pairs, bombs, paint balls and springs
Hard and Super hard levels test your planning, and every chapter has Boss levels where the board turns every three moves.
