Tournament - Abaku School League (13th edition)

Join the nationwide online tournament where enthusiasm and perseverance decide the outcome.

The Abaku School League brings calculation into a game environment, where every correctly solved task moves both the player and the whole school higher in the league table.

Players compete on a 15 x 15 game board with 110 pieces and a time limit of 1 minute per move.
Each player can play a maximum of 21 league duels per week.

The tournament takes place in the Abaku LAB application, where the standing in the league tables can be followed continuously - weekly, monthly, and annual.

On this page, we show the total number of solved examples for each school and player across all game modes (Just Like That, Robot, League).
Every example counts. Every move matters.
Whoever solves the most will not get lost.

League tables of the total number of solved examples in the current school year

Only examples played in games with at least two players are counted in the tables.
The tables are updated once a day in the evening.

Prize: The first 10 schools that solve 100,000 examples will receive an exclusive wooden Abaku Spin board game.
