A block push puzzle where every board has one solution shorter than all the others, and finding it is the game. Push the boulders into the niches in no more pushes than the dashes above the board allow.

The moment the pushes are no longer enough, the board tells you at once: start over, or keep going for practice.

The limit is exact
It is not an estimate: it is the shortest solution, found by trying every path. If a board says 12 pushes, there is a way in 12, and none shorter.

A daily board, the same for everyone
A new board every day, the same for everyone who plays. Unlimited attempts, and your first result is the one that counts. Your streak counts the days you close, and forgives a skipped day. The calendar keeps the past boards, to play when you like; one closed late does not count for the streak. Close the board and an image to share tells how it went without giving the board away.

Four places, one rule more each
The riverbed has only boulders and niches. The ford adds arrows, cells you can only enter one way; the quarry adds colours, boulders that only fit their own niche; the pass adds a door that stays open while a boulder sits on its plate. Each rule arrives alone, on a board made to show it, and then joins the ones before. Ten boards in order open each place, and after them come thousands of boards, always new. Once a place is behind you, you can choose hard boards.

A hint that doesn't solve it for you
A board won't give? After a short video, the hint shows where the boulders must be right after the push nobody would think of: where to get to, not how. Only when there is no such push left does it show the next one.

Survive
Boards in a row, as long as time holds: every board you close gives time back, and the rules are those of the places you have played. It is the only place in the game with a clock, and you only go there if you choose to.

Learned by playing
A block push puzzle with no tutorial to read: three opening boards teach what you need.

What the game doesn't do
A logic puzzle with no account and no telemetry of its own: what leaves the phone is only what Google's ads and Play Games need. Ads, from Google AdMob, never appear in the three opening boards or during a run. There is a banner at the bottom of the board in the four places and on the daily board, and the short video before a hint is an ad you choose to watch: no other full-screen ad.
