Fling pebbles, topple towers, flatten the Grumps. A free arcade game from Corollary’s starter collection that plays right here in your browser, with nothing to download.
Goal: the Grumps (green squatters) have nested inside towers of wood, stone and glass. Knock every Grump out of the level before your pebbles run out. Four levels, three stars each; you keep 3 tries for the whole run. D-pad UP / DOWN: raise or lower the launch angle (6 to 82 degrees), 3 degrees a press. D-pad LEFT / RIGHT: less or more power, 4% a press. The dotted arc shows exactly where the pebble will land — it is computed with the same physics that flies it, so it does not lie. A: fire. After GAME OVER, A starts a new run. During the settle, A skips the wait. B: while aiming, B swaps which pebble is loaded (BOLT / SPLITTER / ANVIL). While the pebble is in the air, B triggers its one special: BOLT speeds up mid-flight, SPLITTER breaks into three, ANVIL kills its forward speed and drops straight down with triple the mass. START / Enter / SPACE: same as A (fire). SELECT / Escape: rebuild the current level from scratch and give back its shots. TAP the playfield: aim at that point — it solves the ballistics and picks a flat shot, or a lob when a wall is in the way. TAP below the ground line: right half fires, left half swaps the pebble. Scoring: Grump 1000, stone 150, wood 100, glass 80, plus 500 for every pebble you did not need. Hitting a structure's weak point (the glass leg, the glass span) brings the whole thing down and pays far better than hitting the roof.
On a phone or tablet, use the arrows and the A and B buttons under the game. On a computer, use the arrow keys and the A and B keys.
