Yours to keep, like games used to be
Each game is a file you own, not an account you rent. New editions are new $1 purchases, and every edition you buy keeps working.
- Buy the game for $1. Or all fourteen for $14.
- Download it. On a computer, save the file and open it in any browser. It works offline from then on.
- On iPhone or iPad, use the web address in your receipt. Open it in Safari, tap Share, then Add to Home Screen. It installs like an app and plays with no internet.
- Pick Kids or Grove 18+. The switch at the top changes every game's rules. Grove is harder, not grown-up content.
Reasons to come back
- Today's challenge: one board for everyone in the world, every day, in Kids and Grove rules.
- Medals for beating the easy, medium and hard computer, in each rule set.
- Rungs from Seed to Grove that grow with your medals.
- The Field Guide: a card about real AI for every game you finish.
- The Stumper's Stumped pile: everything that stumped you, to try again.
Kids rules and Grove 18+
- Kids rules are made for the age on each game, 5 and up.
- Grove 18+ rules are harder: bigger boards, more choices, harder questions.
- No gate, because nothing in Grove is unsuitable for kids. A kid who climbs there has earned it.
World leaderboards, if you want them
- Off until a grown-up turns them on behind a grown-up check.
- Only a made-up name like “Swift Otter 482”, the game, the seed and the moves are sent; our server replays the game to check every score.
- No real names, email, chat or location. One tap deletes a device's scores.
Made for touch
- Big tap targets, nothing that needs a mouse, portrait or landscape.
- Tested by tapping through 208 full games on iPhone, iPad and desktop sizes.
- No ads, no in-game purchases, no tracking, and nothing that flashes.
