Run the Gauntle(t)

How to play

A picture puzzle. Clues tell you how many consecutive filled cells are in each row and column. Reveal the picture.

Each number is the length of a run of consecutive filled cells in that row or column. Multiple numbers mean multiple runs, in order, separated by at least one empty cell. So "2 1" in a row means a run of two filled cells, then a gap, then one more filled cell. Click a cell to fill it; click again to mark it × (definitely empty); click once more to clear. Drag across cells to fill a whole run at once. Clue numbers fade as you place their run correctly; a row or column border turns red if you've over-filled it. "Undo" steps back your last action. "Reset" clears the whole board (Undo brings it back). "Reveal cell" (+5s each) arms the grid so the next cell you tap is set to its correct state. "Check for issues" (+30s, free after that) highlights the rows and columns containing a mistake — it won't tell you which cell.

No timer, no scoring. This is just to learn.
