Cellrun: Beat the Clock
Three minutes, as many 6×6 Medium Cellrun boards as you can. Solve one and the next appears right away.
The clock never stops, not even if you switch tabs. Stuck? Skip costs nothing but the time you spent. Hints and Check work as usual.

How it works
You get three minutes. Every board is a fresh 6×6 Medium Cellrun board with exactly one answer. Your score is how many boards you solve; between two runs with the same score, the one whose last solve came with more time left wins.
