Take a turn. One random block is yours to move and rotate. Drop it, then invite someone else to continue. Each turn adds exactly one block.
Work together on the target. A matching shape anywhere counts; extra cells are allowed. Only blocks added since this target began can complete it. Earlier targets remain as obstacles and support.
Nothing clears, including full rows. After all six targets, keep building. When a new block cannot enter, the shared board becomes the finished artwork. Name it and save a PNG.
Press Leave this turn to pause the same unfinished block for someone else. If the block is still unfinished after 30 seconds without control input, the turn pauses automatically. While your turn is active, gravity can land your block. The board is saved in this browser when local saving is available.

This replaces the current board on this device. Keep this work by cancelling; a finished work can be saved as a PNG first.
