What it is

Domino Circuit is a single-player puzzle game about one chain reaction. Each board is a line of standing dominoes that is mostly built already, with a few gaps in it. You get a small handful of domino sections, straights, corners and forks, and decide where each one goes and which way it faces.

Then you press Push and watch the dominoes fall along your route, from the start marker outwards. Every gold star has to fall in the same push. A board often has more than one gap a fork could fill, so the puzzle is working out which gap needs it.

Tap a piece and then a gap, or drag it there. There is no timer and no limit on attempts.

What is in it

  • 30 circuits. Hand-made boards in five chapters, each checked to be solvable. The first three explain the controls. Finish a circuit to open the next. Circuit 19 is open from the start, for players who want to skip ahead to a harder one.
  • Try again freely. Adjust keeps your pieces where they are after a push that missed. Undo takes back your last change, and Restart gives you a fresh board. There are no lives.
  • Hints. A hint shows where one piece goes and which way it faces. It stays yours, even after a restart, and reopening it is free.
  • Settings. Sound on or off, and reduced motion, which shows the result of a push straight away.
  • Offline. All 30 circuits are in the app. You can play without a connection and without an account, and the game remembers where you left off.

A hint on circuit 13, Save the fork. It shows a corner in the outlined gap, connecting north and west, and says other pieces may still need moving.

Price and coins

Domino Circuit is free to play. Undo, Adjust and Restart cost nothing. A hint costs 25 coins. You start with 50 coins and get 10 more the first time you solve each circuit.

If a push misses, the hint screen can offer an optional video advert for 25 more coins. Watching is never required, and every circuit can be solved without a hint. There are no purchases in the game.

Privacy

Domino Circuit has no accounts and no crash reporting, and it sends no analytics. Your progress, and a record of your play that you can export, stay on your device. Adverts come from Google AdMob, and an advert loads only when you choose to watch one. The Domino Circuit privacy policy sets out what the app stores, what it sends and to whom.
