About Acorn Trail

Acorn Trail is a turn-based puzzle game on a grid. An otter and a goat both have to reach the same burrow, and you move them one at a time. Tap an animal, then tap where you want it to go. Nothing moves until you do, so there is no timer, and every critter on the board takes one step each time you take one. You can play it in this browser right now.

It has been on the App Store for iPhone and iPad since 7 November 2026, listed as Acorn Trail: Otter & Goat. The Android version is coming to Google Play, and until then the browser version is the way to play it on Android.

The two animals are built to need each other. The otter swims ponds and slides across frozen ones; the goat walks on ice, pushes logs and squeezes through thorn gaps too narrow for an otter. Acorns open the hollow-log gates, and a mushroom pad has to be stood on to open the hedges, which takes one animal while the other goes through.

There are sixty levels across six meadows. The first eight are the tutorial, one new thing each, and a short walkthrough you play rather than read sits behind “Show me how”. The last ten boards are bigger than the screen, and the view follows the two animals. Every level shows the fewest moves it can be done in, measured by a solver, and awards one, two or three leaves for how close you came.

A try can be lost: a critter catches one of your animals, or you run out of moves, and each meadow gives you fewer spare moves than the last. But undo is free and unlimited, and there are no lives. The board marks in red the squares a critter is about to step onto, so nothing catches you by surprise. If a level stops being fun, the game offers to let you walk on past it.

Acorn coins come from solving levels and nothing else. They buy six looks for the meadow and change no rule. You can’t buy them, and they aren’t like the coins in our reward apps, which come out as PayPal cash. There is also a level builder: draw a board, and the same solver checks it can be finished before it saves.

How it plays

Tap an animal. Then tap where you want it to go and it walks there, a square at a time. Tap the other animal to take it instead, which costs nothing.
Use what each can do. The otter swims; the goat pushes logs, walks on ice and fits through thorn gaps.
Open the way. Collect acorns for the log gates, and stand on a mushroom pad to hold a hedge open for the other.
Watch the red corners. They mark where a critter is about to step. Wait is a move too, for letting one go past.
Get both home. In fewer moves for more leaves. Undo as much as you like.

Frequently asked questions

Can I get Acorn Trail on the App Store or Google Play?

On the App Store, yes: it has been there for iPhone and iPad since 7 November 2026, free, as Acorn Trail: Otter & Goat. Google Play is still to come. Until then you can play it in this browser for free, with nothing to install.

Does Acorn Trail pay me anything?

No. The acorn coins in it buy looks for the meadow and nothing else. You earn them by solving levels, and they can’t be bought or spent anywhere outside the game. Our apps page lists the ones that pay.

Can two people play?

Yes, on one phone, tablet or computer: choose Play Together and take an animal each. The rules and the levels are exactly the same as playing alone. The iPhone version adds a third way, two phones on the same Wi-Fi with an animal each, which a browser cannot do.

Who is it for?

Anyone who likes a puzzle, and a child can play it. The tutorial is eight short levels and a walkthrough you play. Undo never runs out, and nothing is locked behind a purchase or an ad.

Can you lose?

A try can end, if a critter catches one of your animals or you run out of moves. Take back the last move or start the level again; there are no lives and nothing is ever locked. The board marks in red the squares a critter is about to step onto, so a catch is never a surprise.

Does the browser version have ads?

No. There is no browser version of the ad network, so nothing shows, and the hint, which the iPhone version offers for a short video, is free here. The iPhone version carries a banner on the menus and an ad after every fourth level you finish, never during one.

Does it save my progress?

Yes, in this browser. It keeps levels solved, leaves, acorn coins, themes, badges and the levels you build. They aren’t tied to an account, so a different browser or device won’t have them. A private window, or clearing site data, loses them.

Can I share a level I built?

Yes, as a code: the builder turns your board into a short piece of text anybody can paste into their own copy. Sharing by link needs the store versions.
