A short daily puzzle. You get 16 tiles that hide four groups of four, and four tries to find them all. Everything on the board comes from the CAPS syllabus, so it is revision that does not feel like revision.

One a day, every day, and it changes at midnight South African time. There is only one puzzle a day, so once you finish it you are done until tomorrow.

Only things you have already been taught. A Grade 10 puzzle can use work from any grade up to and including Grade 10, and never anything above it. The easiest group usually comes from a lower grade, and the trickiest one sits at your level.

Yes, it is free, and there is no sign-up. Your streak and your part-finished board are saved in your own browser, not on our servers.

Use Shuffle. Moving the tiles around breaks the picture you have got stuck on, and the group you were missing often jumps out. If a guess has three tiles from one group, we tell you that you were one away.

They rank how hard each group was meant to be, from yellow for the easiest to purple for the trickiest. One group is always a bit of a trick, so if three fall out quickly and one will not, that is the one to think about differently.
