Sequel has only one rule: tap the sequel - the shape that is different from the last in exactly ONE way. Don't tap the same shape twice in a row; and don't tap any shapes that differ in two or more ways.

Shapes will flash on your screen with different numbers of sides, fill colors, border colors, border thickness, numbers of dots, and more varieties you'll discover at later levels. Sounds simple? You've got to have a good memory and to stay focused!

Share your Sequel scorecard - and challenge your friends to beat your personal best.

Multiple game modes:
• Classic - start with only a few shapes with simple differences, and work your way up to all the different varieties
• Time Trial 5 minutes - Go for speed and get the largest sequence in 300 seconds.
• Time Trial 3 minutes - Do the same in 180 seconds.
• Hard Mode - Start directly on level 10, dozens of shapes ahead of a regular game.
• Training Wheels - Two extra chances to make mistakes without having to start over.
• Mysteries of π - Try it out to find out what it does.

This version is free-to-play and ad-supported. In-app purchase of choose-your-price Deluxe upgrades can be used to get rid of banner ads and get a special scorecard badge for bragging rights. Find the pay-once edition of Sequel at

• For a particular attribute (say number of sides), the amount of difference is irrelevant. For example, a pentagon (5 sides) is indeed the sequel of a triangle (3 sides) if all of the other attributes are the same. For more info, see
• The game will be easier if you use standard color settings - otherwise it may be more difficult to tell colors apart.
