Super-Charge your Word Building But avoid the Fletter Fuse bombs! In Fletter Fuse, 2-6 players have to fuse Single, Double and Triple letters together to make words. Everyone plays at the same time, so you have to think fast and act faster than your opponents if you want to win. The aim of the game is to make the most points. Players toss cards with letters into a joint pool. The first player to see a word of 5 letter or more, shouts the word out and collects the cards. Once the deck runs out, the cards are added up and the player with the most points wins.
