How to play
This is a game for two or more players. Each played needs a tablet, computer or smartphone with this page loaded.
If you have ever played a card game called Top Trumps you will know the main idea of this game already. Each player clicks the 'next shape' button (while the other player isn't looking) and the computer selects a shape at random. The players each choose a property that they would like to play with and click that button.
The players can now look at each other's shapes and the scoring is worked out. Whoever has the largest value for player 1's property wins one point. Also the player who has the largest value for player 2's property wins one point.
Now each click the 'next shape' button for round 2 and repeat the choosing and scoring process.
The first player to win ten points is the overall winner.
The names and numbers in the Score table are editable so you can change them.
You could play this game if you only have one computer between the two players. Open a copy of this page in two different tabs or instances of the browser. Each player looks away while the other player selects their shape and property.
