Word Dominoes
Arrange tiles holding two word halves into a closed loop. The right half of each tile joins the left half of the next to make a compound word, and the last must join back to the first. Spare tiles stay in the tray, so finding the right words matters as much as their order.
How it works
- Join each tile’s right half to the next tile’s left half to make a compound word.
- Close the loop: the last tile must also join the first. Tiles keep their direction.
- Tap a tray tile to fill an empty slot. Drag to rearrange, swap or return tiles.
- Check as often as you like. Ticks mark valid joins; crosses mark joins to rethink.
- A hint places one tile correctly. Undo and Clear keep your checks and learned joins.
Good if you want…
- Spotting compound words
- Trying arrangements without a mistake penalty
- Word puzzles with a little spatial reasoning
How to solve Word Dominoes
Read each tile inside out
Every tile already spells a compound, spares included, so NOTE | BOOK reading as NOTEBOOK tells you nothing. The words that count sit across the gaps. A tile's left half finishes the word coming in and its right half starts the word going out. NOTE | BOOK wants a tile ending in FOOT before it, for FOOTNOTE, and one starting with CASE after it, for BOOKCASE.
Some halves only face one way
SUN, SNOW and MOON start plenty of compounds but end hardly any. LESS, MAKER and KEEPER are the reverse. A loop tile needs a word ending in its left half and one starting with its right half, so a tile with SUN on the left, or LESS on the right, is almost certainly a spare. For the rest, count partners. A right half like OUT could precede several left halves on the board and settles little. One that fits a single tile gives you a join to build from.
Find the spares
Easy and Medium leave one tile out, Hard two and Expert three. Each spare fits the loop from one side only: some loop tile could sit before it or after it, never both. On Easy the spare is weak and usually matches a single tile. From Medium up, spares are picked to fit as many loop tiles as they can on their live side, so a tile with lots of options one way and none the other is the classic spare.
No half appears twice in the loop. If two tiles share a half, on either side, at least one of them is out, and on Expert both often are. A spare's dead side can also meet another spare, so judge each tile by what it could join among the loop candidates, not the whole board.
Grow a chain and let the loop close
The loop has no first tile, and any rotation counts. Place your surest join anywhere and extend it both ways: forwards by asking what the last right half can start, backwards by asking what could end in the first left half. The final gap is the strictest, because its tile must make a word with both neighbours. If nothing fits there, the fault is earlier in the chain.
Make every check count
Check never compares your loop with the answer. It asks the dictionary about each join with both tiles placed, including the one from the last slot back to slot 1, and that dictionary is wider than the list the loops are built from. Real words that don't belong get ticks: OUT will make OUTSIDE, OUTHOUSE or OUTWORK with tiles meant for elsewhere. An Expert board often holds a dozen or more of these.
Checks are unlimited and a cross costs nothing, but the count is kept, so fill every slot before you press. Marks belong to the pair in that order. Put two checked tiles side by side again and the tick or cross returns without another check. A finished loop only counts once you press Check.
Common mistakes
- Treating a tick as settled. It only says the two halves make a word. When the loop won't close, question the ticked joins as well as the crosses.
- Reading a join backwards. Tiles never turn, so each word is one tile's right half followed by the next tile's left half.
- Forgetting the closing join. A chain that reads well from slot 1 to the last slot isn't a loop until the last tile leads back into the first.
- Checking one pair at a time. Every press is counted, and a full ring tests all its joins at once.
Word Dominoes questions
Can more than one loop be right?
No. Each board is proved to have a single loop, counting every word the dictionary accepts. The same loop shifted round the slots is the same answer. Running it in the opposite order pairs different halves and fails.
What counts as a word?
Compounds written as one word, from a British English spelling list, so COLOURFAST counts and the American spelling doesn't. Every half is a word in its own right, at least two letters long. There is no theme linking a loop's words.
What does a hint do?
It places one loop tile, marked with a dot, working from slot 1. If slot 1 holds a loop tile, it stays and the hint fills the lowest-numbered slot that isn't right yet. If slot 1 is empty or holds a spare, the hint fills slot 1. So put the tile you trust most there first: if the hint replaces it, you have found a spare. A hint never checks, so you still press Check to finish.
