TREASURE!- The level is lost as soon as all 5 slots are full of imps that can't mine anything, even if a lane could still send a group that would.
- Each lane lists its groups in single file, one per row, top group first and largest.
- All 12 levels are re-proven under the stricter rule. The slots tutorial (level 3) has new lanes so it stays a gentle lesson, and its tip now says how you lose.
Five stuck slots lose, and lanes in single file
