Free · No sign-up · Phone or computer
Place tiles next to the ones on the board. Every row and column your tiles touch must add up to exactly 10.
Each line you complete is worth 10 points. One tile can finish two lines at once. Coloured squares multiply or add points.
Play one move per try; your best counts. Then see how close you came to the highest possible score.

The sums are small, but they never stop. To find a good move you add along every row and column you touch, look for pairs that make 10, and check that one tile doesn’t push another line over. A big move might complete four or five lines at once, and finding it means holding all of them in your head.
That makes it quick mental-maths practice for adults, and a fun way for kids to learn number bonds to 10. A puzzle takes a couple of minutes, and the streak brings you back tomorrow.
Once a day is over, its board and the highest-scoring move go into the archive, so you can check how close you came.

Adding up to 10: number bonds like 3 + 7 and 2 + 8, mental addition across three or four tiles, and planning which numbers go where. Every line adds up to exactly 10, so the sums stay small and the challenge is in fitting them together.
If they can add to 10 in their head, they can play. The rule is simple enough for a child, and finding the highest-scoring move is hard enough for adults.
