PlunkDrop

A calm physics puzzle in black ink on paper. Drop a shape into the beaker. When two of the same shape touch, they fuse into the next one up. Plan the pile, set off chains, and keep everything under the line.

Two ways to play

Daily

The same 80 pieces for everyone on the same date. Drop them all without spilling over, share a one-line result, and build a streak by playing each day.

Endless

Play until the pile spills over and chase your best score.

Ten shapes

Dot, bar, triangle, square, pentagon, hexagon, cross, star, target, ring. Each reads by its outline, not its color. Two rings clear each other for a bonus.

A Daily in play: a pile of ink shapes in the beaker, the next shape held over the rim
