Tetra Tower

You stack chunky plastic blocks onto a platform that tilts on a central pivot, and the person who brings the whole tower down loses. Draw a card, find the block whose shape matches the picture, and set it on the pile wherever you think it will hold. The base rocks a little with every piece, so a block that looked safe on your turn can be the one that shifts everything on the next. There is nothing to learn and no reading, which is why we bring it out for the youngest children in the café and for adults who want something loud between two proper games. A collapse takes about five minutes to arrive, and it works with any number of people around the table. Think of it as Jenga with a wobble.
