Why the practice rules are visible
In the original game, discovering rules is part of the challenge. Here we tell you the rules so you can learn complete set membership first. The skill being practiced is checking every piece, including the ones outside and in overlaps.
Accessible, deliberate practice
Every shape is labeled with its color, fill and type, so color alone is never the only clue. Use a mouse, touch, or Tab and Enter/Space. Select a tile and then select a destination. You can reassign a tile at any point before checking.
Completely separate from Mindset Go!
This Rule Lab is our original educational tool, not an official game mode, an unlimited version, a solver or an answer feed. It runs locally and does not save progress or send your moves anywhere.
