Four Letters is a puzzle game where players have to create four-letter words by using the letters given to them in each new puzzle.
The objective of the game is to create as many words as you can before time runs out. And, the quicker you create the words, the faster the clock will go. So, even if at the beginning you have time to look at the letters and think about all the words you can create, once you create 20 the clock will be running extremely fast.
As you might expect, the four letters you use to make one word can also be used to form a different one. Sometimes you might even be able to make four or five words with the same four letters, while other times only one or two are possible. It will all depend on the letters you're given. When you lose a game, you'll be able to see the words that you could've formed with the letters you'd been dealt. You'll often do the face palm when you see what you missed.
Four letters is an excellent puzzle game where you play short games that last one or two minutes (that's if you're good at playing). The best part of the game is that it's a pretty original idea in a genre that's full of many games that just copy one another.
