Eureka is a puzzle game where your goal is to arrange gems (which come in various types) into specific designs. The design you have to make is on the left of the screen, and your current arrangement of gems is on the right. By clicking on a gem here, you turn it into another type of gem - when you click it multiple times, it cycles between various types of gems (the sequence is shown at the top of the screen) and finally disappears, with all the gems above it falling down. Clicking on a gem also changes the four games around it - but these neighbouring gems cycle forward by two types of gems instead of one.
There are 50 levels. If you get stuck, you can press Space to restart the level, but you have a life when you can do this. If you run out of time, the level restarts and you lose a life, too.
