How to play
Tap a block in the tray, then tap its place in the arch, working up from both sides in turn. Each block, cream or red, fits one place only and holds only if the block below it is already set; otherwise it wobbles, falls back to the tray and counts as a small mistake. The last block is the keystone at the top: the wooden centering drops away and the arch stands. Before each level a card explains the type of arch and the words: voussoir, keystone, centering. On the keyboard: the Left and Right arrow keys choose the side, and Space or Enter places the next correct block (and also closes the card). Three levels; points depend on few mistakes and speed.
