Ultimate Brain Games is an unreleased board video game that was in development by Teque London and planned to be published by Telegames on a scheduled Q2 1995 release date exclusively for the Atari Jaguar. The game was going to be a spiritual successor to Fidelity Electronics and Telegames's 1991 Atari Lynx title The Fidelity Ultimate Chess Challenge. It was also intended to be released the Atari Jaguar CD add-on and later on the PC.
