Hoard Master

No download, no account: Hoard Master is a Puzzle game that runs where you found it. Taps and swipes are the whole vocabulary — a phone plays it best. Its tags here are avoid, collecting, kids, mobile, skill.

It is drawn for a tall screen, so it fills a phone held upright rather than a wide monitor. Nothing is saved to an account, because there is no account — progress lives in this browser.
