How to play Domino Logic
The board is a grid split into coloured regions. Under it sits a tray of dominoes — exactly the dominoes this board needs, no more and no fewer. Your job is to place every domino so that every region rule is true at the same time.
- Pick a difficulty — Easy (4 by 4 grid, 8 dominoes), Medium (5 by 4, 10 dominoes) or Hard (6 by 4, 12 dominoes) — and press Play. Or press the Daily Puzzle button for today’s puzzle. On Hard, three dominoes start already placed and locked: they are givens, part of the puzzle itself, and they cannot be moved.
- Tap a domino in the tray to select it, then tap a cell on the board. The domino is placed from that cell towards the right. Press Rotate (or the R key) to place upright instead. You can also drag a domino straight from the tray onto the board.
- Tap a selected domino a second time to flip its ends around before placing it. Getting the right number on the right cell is the whole game.
- Tap any placed domino to pick it back up into the tray. There is no penalty for changing your mind — only the clock and the optional Check and Hint buttons affect your score.
- Read the little tag on each region. It tells you the rule for that colour. Tags turn green when a finished region is correct and red when a rule is broken or can no longer be reached. Fill the whole board with every tag green and the puzzle is solved.
One promise before you start: every puzzle in this game has exactly one solution. Each board was generated by our own puzzle maker and then proven by a solver program, which checked every possible placement and confirmed that only one arrangement of the tray satisfies all the rules. If you are stuck, the answer is never “the puzzle is broken” — it is always hiding in the rules.

The five region rules
Every region wears a tag with one of five rules. The rule always covers every cell in that colour — including cells covered by dominoes that started in a different region. A domino can sit across two regions, and each of its halves counts only for the region it lands in.
| Tag | Rule | Example |
|---|---|---|
| = 12 | The pips in this region add up to exactly the number shown | Cells showing 5, 4 and 3 solve an = 12 region |
| ALL = | Every cell in the region shows the same number of pips | Three cells, all showing 2 |
| ALL ≠ | Every cell in the region shows a different number — no repeats | Cells showing 0, 3 and 5 |
| > 9 | The pips in the region add up to more than the number shown | A total of 10, 11 or more |
| Under 14 | The pips in the region add up to less than the number shown (the tag shows a less-than sign before the number) | A total of 13 or less |
Two rules of thumb. An ALL = region with three cells needs three matching halves — and only doubles and lucky tray mates can supply them, so check the tray before you commit. An = sum region is usually the tightest rule on the board: solve those first and the looser over and under regions often fall into place around them.
Scoring, hints and checks
Your score rewards speed and clean thinking. Every puzzle starts with a base score, and a time bonus counts down from the moment you start — so a fast, clean solve is worth far more than a slow one.
| Difficulty | Base score | Time bonus |
|---|---|---|
| Easy | 300 points | 2 points per second under 2 minutes 30 seconds |
| Medium | 500 points | 2 points per second under 5 minutes |
| Hard | 800 points | 2 points per second under 6 minutes |
| Daily Puzzle | By its difficulty | Plus a flat 100 point Daily bonus |
Two helpers are always on hand, and both cost points. Check (30 points) tells you exactly how many of your placed dominoes are wrong — never which ones, so you still have to find them. Hint (75 points) takes one domino from the tray and locks it into its correct place with a gold outline; locked dominoes cannot be picked back up. Your best score, the puzzles you have solved and your Daily streak all save in your own browser, and your streak grows when you solve the Daily on consecutive days.
7 tips for domino detectives
- Start with the tightest rule. Exact-sum and ALL = regions leave the fewest options. A three-cell = 6 region can only be 0+0+6, 0+1+5, 0+2+4, 1+1+4, 1+2+3 or 2+2+2 — check which of those the tray can even make.
- Count the tray, not just the board. The tray is exact. If a number appears only twice in the whole tray and a region needs it three times, your plan is wrong before it starts.
- Doubles are precious. A double (both halves the same) is the only domino that can put two equal pips side by side. ALL = regions and paired cells in exact sums usually want them.
- Watch the red tags. A tag turns red the moment a rule becomes impossible — even before the region is full. That is free information: the last domino you placed near that colour is a prime suspect.
- Work the edges. Corner and edge cells have fewer neighbours, so fewer dominoes can cover them. Placing edge dominoes first cuts the board’s options down fast.
- Check before you hint. Check costs 30 and Hint costs 75. If Check says only one domino is wrong, hunting for it yourself is usually cheaper than a hint — and finding it teaches you the board.
- Protect the streak cheaply. The Daily can be any difficulty. On a busy day, solve it slowly and cleanly rather than racing: the streak counts the solve, not the score.
Is Domino Logic free and safe to play?

Domino Logic is an original game made by GameOLL.

Domino Logic FAQ
Is Domino Logic free to play?
Yes. Domino Logic is 100% free. You play it right on this page in your browser. There is no download, no sign-up and no payment.
How is this pips game different from a daily newspaper puzzle?
A daily puzzle gives you one board a day. Domino Logic gives you a bank of 30 proven puzzles across three difficulties, plus a Daily Puzzle of its own, so you can keep playing. Every board is generated and solver-proven by GameOLL, and the game is not affiliated with any newspaper.
Does every puzzle really have only one solution?
Yes. A solver program checks every puzzle before it joins the bank. It tries every way the tray could be placed and counts the arrangements that satisfy all the region rules. Only puzzles with exactly one working arrangement are kept. On Hard boards, where three dominoes start already placed as givens, the solver proves there is exactly one way to complete the board.
What do Check and Hint do?
Check costs 30 points and tells you how many of your placed dominoes are wrong, but not which ones. Hint costs 75 points and locks one tray domino into its correct place with a gold outline. Locked dominoes cannot be picked back up.
How does the Daily Puzzle streak work?
Every day has one Daily Puzzle, picked from the bank by the date. Solve it and your streak grows by one. Miss a day and the streak restarts at one on your next Daily solve. Solving the Daily also adds a flat 100 point bonus to that puzzle’s score.
Can I play Domino Logic on my phone?
Yes. The game is built for touch: tap to select and place, or drag dominoes from the tray onto the board. It also works with a mouse and keyboard on laptops and desktop PCs.
Final verdict: should you play Domino Logic?
Yes — if you like logic puzzles where every move is earned. Domino Logic takes the region-and-domino idea and removes the one-a-day limit: 30 solver-proven puzzles, three difficulties, a daily streak to protect, and a score system that rewards clean thinking over lucky tapping. No download, no account, no waiting until tomorrow. Pick a difficulty and place your first domino.
