Behind the curtain sits a hidden Purble (game character). You have to figure out what it looks like by building a model. Select features from the shelf on the right and add them to your model. When you have the right features (such as hair, eyes, hat) and the right colors, you win the game. The game is appropriate for older children or challenging enough for adults, depending on the difficulty level selected.
The scoreboard will tell you how many features are correct. If you need help, click on Hint - it will tell you which features are wrong (but not which ones are right).
Watch the score change with each feature you add or take away – that will help you figure out which ones are right and which are wrong. Once you have one of each feature on your model Purble, click the Guess button to see if you've matched the hidden Purble.
