Chase It is a homebrew Atari 2600 game developed by Alan W. Smith and released in 2010. The game was later included in the Atari Flashback series of plug-and-play consoles, starting with the Atari Flashback 5 in 2014, and most recently in the Atari Flashback X Deluxe in 2019.

In Chase It, two players (or one player and the computer) must move around the arena and touch a red square before their opponent. After this, the red square(s) move to a random location, and the first to touch it 99 times is the winner.

A selection of 20 game modes add variety to the gameplay; including adding a second red square, making the red squares move, adding obstacles to the arena, and changing the speed of the computer opponent.
