Welcome to Rocolex!

What is Rocolex?

Rocolex is a free online number game for two players, based on a paper game played at school. The board is a 7 by 7 grid of numbers, some positive and some negative. One player picks from the rows, the other from the columns, and every number you pick is added to your score. The twist is that each pick decides which line your opponent must play from next, so the biggest number is not always the best one.

Every game is a quiet workout in mental arithmetic and planning ahead. You can practise against a bot, challenge a friend, climb the world leaderboard, or run a private league for your class or club.
