World Efficiency Cup 4

World Efficiency Cup 4 is a community-run efficiency competition that will take place from November 23 to 29, 2026 (UTC), inclusive.

There are separate rankings for Beginner, Intermediate and Expert, each based on each player’s 4 best games on boards of the corresponding size during the competition. There is also a main ranking that combines all three.

To qualify for a ranking, you need to complete 4 games at or above the target efficiency for that board size. If you qualify for all three rankings, you will also be included in the main ranking. The target efficiencies are:

• Beginner: ≥ 160.00%
• Intermediate: ≥ 135.00%
• Expert: ≥ 120.00%

After completing a game, submit it to EffCupBot to have it included in the rankings. You can submit as many games as you like during the competition to update your scores. To keep the rankings as up to date as possible, games must be submitted within 2 hours of completion to be accepted.

The prize pool consists of at least 50k topaz, with prizes based on scores and placement in each ranking, as well as additional minecoin prizes for reaching certain scores in the main ranking.
