The weekly challenge: the hardest Tango grid of the week
Every Monday at midnight, Paris time, a Master-level 10x10 Tango grid is published, the same for every player. You get a single attempt for the whole week: your score depends on solving time and hints used, and feeds the weekly leaderboard.
To improve before taking it on, check the solving techniques or practice on the unlimited 10x10 grids.
When does the weekly grid change?
Every Monday at midnight, Paris time. The same grid stays live all week, identical for every player.
Why is the weekly challenge so hard?
It is a 10x10 grid calibrated at Master level: few starting clues, and solving it requires the advanced techniques, including the one-move test. It still has a unique solution, reachable without guessing.
How do I prepare for the weekly challenge?
Practice on the unlimited 10x10 grids and work on the solving techniques: quota counting, clue propagation and the one-move test.
