Make it 13!

No download, no account: Make it 13! is a Puzzle game that runs where you found it. Taps and swipes are the whole vocabulary — a phone plays it best. Catalogued as 2d, arena, best, color, coloring.

It is drawn for a tall screen, so it fills a phone held upright rather than a wide monitor. Close the tab and come back later; the game is still one click away.
