Mayhem is a fast paced action game. The player has to control Wizzy while trying to collect coins. At first, just one flying stick will be flying around the screen, but as the coins are collected the game becomes harder, with more and more sticks flying around (added first at 5 points and then after each 10 points). For consoles equipped with The Voice module, an alert is emitted when a new stick is added.
The game also features a secret hidden gameplay mode, internet highscore uploading and an online rewards system. To upload the highscore, players receive a code which must be entered at the developer's website. The online rewards work the same way, and there are four of them:
- [silver] Mayhem much? - Play 100 games of Mayhem in one session
- [bronze] Emperor's new clothes - Play a game using the alternate costume
- [silver] Lickety-split - Reach chaos level 6
- [gold] Chaosmaster - Reach chaos level 8
