Play an original, five-stage browser take on Gonggi, the Korean five-stones game. Gather the stones one at a time, then in pairs, triples and fours before trying the final Kkeokgi timing challenge. Touch, mouse and keyboard controls are built in.
A toss lifts the keeper stone. During its flight, select the requested group from the stones on the mat, then catch the keeper when it reaches the marked window.
Clear stage 1 by picking one stone four times; stage 2 uses pairs, stage 3 uses three and then one, and stage 4 gathers all four at once.
Stage 5 is a digital Kkeokgi variation: time a catch on the back-of-hand pass, flick the stones again, then time the final catch. Three mistakes end the stage.
