TahminYo is a Turkish prediction and entertainment platform where users put their knowledge of sports and current events to the test. Members can predict football and basketball results, including match scores, and earn points for their predictions. The platform also features special prediction contests on topics beyond sport, such as the winner of MasterChef Türkiye 2026.

Users can follow active predictions, see how much time remains to enter, and compare performance on a live leaderboard showing points and prediction accuracy. Rankings and member-specific standings are available to logged-in users, while account verification through SMS, email, and Telegram can offer additional points. TahminYo presents itself as a social competition for sports fans, encouraging them to play, collect points, and climb the rankings alongside friends and participants across Türkiye.

It explicitly states that it does not offer real-money betting: points and rankings are for entertainment only. The brand also provides sponsorship and advertising opportunities, including sponsored predictions, banners, and custom events, and shares updates, news, and promotional codes with its community
