Description: Players saw a grid of twelve tangram shapes taken from Clark & Wilkes-Gibbs (1986). The matcher clicked and dragged tangrams to new positions. When confident that their board matches that of the director, the matcher clicked a 'submit board' button and received feedback on the number of tangrams (out of 12) that matched, before advancing to the next round (out of 6). This task was unconstrained in the sense that players could type anything into the chat box at any time and address the tangrams in any order they preferred.
