How to play
Every neighboring pair of words in the chain makes a compound word or a common phrase, like SESAME to STREET to CAR (sesame street, streetcar).
The first and last words are given. Tap a row next to a solved word, type your guess, and press Enter. You can work from the top, the bottom, or both ends.
One letter of every hidden word is already showing. A wrong guess costs a heart and gives away one more letter of that word.
Solve a word on the first try, with no extra letters given away, to earn a dynamite (you can bank up to 3). Tap it twice and it knocks 3 unused letters off the keyboard.
Run out of hearts and you can start the chain over. Link the whole chain to reveal the cache.
