We check every store before it is listed. That check covers the seller, the checkout price, and that the store has a refund path. The refund itself follows that store's rules. We test the checkout so the price on the row matches what the store charges before tax and payment fees. Each offer shows how long ago its price last changed. Hover that time for the exact moment. The price, and whether the store still has the offer, can change after that. The list opens on the lowest price, which is the lowest offer GameGator is listing. Some Buy buttons are affiliate links, and the store may pay GameGator a commission. A region is where that key can be activated. A platform is where the game runs. A wrong price or seller can be reported to support@gamegator.net. We can correct the listing. The store handles delivery and the refund.

OXO was a computer game developed by Alexander S. Douglas in 1952 for the EDSAC computer, which simulates a game of Noughts and crosses, also sometimes called Tic-tac-toe. OXO is the earliest known game to display visuals on a video monitor. To play OXO, the player would enter input using a rotary telephone controller, and output was displayed on the computer's 35×16 dot matrix cathode ray tube. Each game was played against an artificially intelligent opponent.

GameGator compares prices. This description, the release dates, and the age ratings come from IGDB. A later date on another platform is a separate release. A date still in the future is marked as not released yet.
