Add an orb to a square until it bursts into its neighbours and takes them over. Bursts set off bursts. Two to four colours; the last one standing wins.
Against the computer at three levels, or up to four on one screen
Squares one orb from bursting shiver, so you can see the danger
Points for wins against the computer, added up in this browser: 1 on Easy, 2 on Medium, 3 on Hard.
The board needs script to show.
Leaderboards take child-friendly names only. A name is three letters, A to Z, like an arcade high score. Rude, unkind or adult names are refused, and any that slip through are taken down. To report one, email hello@oneappcompany.com.
Your records, best scores, your pet and the three letters you last put on a board are kept in this browser, on this device. A board keeps the letters, the score and when; to stop floods it also keeps a scrambled form of your address, never the address itself.
