Word games & puzzles

Daily word puzzles, letter-path boards, letter-transfer rounds, and early letter practice from Swizzle Works.

Pick by the job. Want two hidden five-letter words on one board? Dualword. Want to move one letter between two words you can already read? Affix. Want to find a path through letters already on a board? Onword. Need letter recognition practice for ages 4 to 7? Fasty Letters, and its guides live on the early literacy hub.

Dualword is free in the browser at dualword.swizzleworks.com. One guess scores against both hidden answers on a split tile. No account. Today's pair is on your device. iOS and Android are still on the way.

Affix is free in the browser at affix.swizzleworks.com. Move one letter so both words match their clues. Five rounds a day. Native store listings are still coming.

Onword is free in the browser and on iOS as Onword Daily. Draw one trail through the letters so each word connects in meaning to the next. Android is not out yet. Its guides split by what you came in asking: the word path puzzle rules and tips walk the tutorial board, games like Strands is for the morning you finished Strands and want the next trail, the connect letters game guide separates a one-trail board from a score attack, and the word chain page sorts out which of three games someone meant.

The guides compare Dualword with other two-word dailies, explain the split tile, and cover getting unstuck. The table below puts every game mentioned here side by side. We are not dumping a million dictionary URLs into the sitemap.

Frequently asked questions

What is Dualword?

A daily word puzzle from Swizzle Works. Guess two five-letter words on one board. Each guess scores against both answers. The top half of a tile is word one. The bottom half is word two. Play free in the browser.

What is Onword?

A daily word-path puzzle from Swizzle Works. Draw one continuous trail through a letter grid so that each word connects in meaning to the next. Play free in the browser or get Onword Daily on iOS.

How is Dualword different from other five-letter guessing games?

A typical five-letter guessing game hides one word. Dualword hides two, and every guess scores against both on a split tile. Dordle uses two boards for that. Xordle uses one board but never lets the words share a letter. The Dordle vs Dualword guide has the table.

What is Affix?

A daily word puzzle from Swizzle Works. Each round shows two words and two clues. Move exactly one letter from one word to the other so both match the clues. Play free in the browser.

What about younger kids?

Fasty Letters covers ages 4 to 7 letter recognition. Different product, different job. The early literacy hub has the letter guides: recognition practice, uppercase and lowercase matching, letter names versus sounds, and reversals.
