Q: What’s to stop someone just picking a cube from the bag every turn, so no-one can win?

A: Usually, players will focus their attention on trying to win, rather than single-mindedly seeking to prevent anyone from doing so. However, if you find yourself with a player who insists on pulling a cube each turn so that no one can ever make any progress, you’ll have to apply what we’re calling the Meltdown Limitation Rule:

Players can only choose the Meltdown option 3 times during the course of the game. Each player starts with a trio of pyramids of an unused color, and must discard one of these tracking pyramids each time they trigger a Meltdown.
