Remember 15-puzzle, the sliding puzzle that challenges you to place the numbered tiles in order by making sliding moves that take advantage of the empty space? Well, Sletters is essentially 15-puzzle, but with letters instead of numbers.
In each level of Sletters, you have to slide tiles in whatever direction the empty space allows with the ultimate goal of forming all of the required words. While you can make as many moves as you need, and can form words in either orientation (horizontally or vertically) and in any order, Sletters puts forth plenty of challenges. If it gets so tough that there seems to be no way out, you can choose to swap tiles.
In each level, you must take advantage of the empty space to slide tiles in any direction. Make as many moves as you need in order to form words.
For each level, there's a list of words that you need to make. This list is displayed before the start of a level, and it's easily accessible as you play so you know what you're aiming for as you make your moves. You can form words either horizontally or vertically, and in any order you wish.
In Sletters, as in other level-based games, some levels are designed to be more difficult than others. This way, you're adequately challenged and encouraged to play more. But if you get stuck on a particularly tricky level, and if you still have a swap power-up left to spend, you can swap the positions of any pair of tiles.
Sletters combines word puzzles and sliding puzzles into one neat brainteaser. Its word-forming and tile-sliding mechanics are dead simple, but its levels include stumpers that really dare players to swap tiles lest they reach a dead end. But stuck or no, players can always rely on the game’s vibrant colors and ragtime-inspired music to keep the mood bright and cheery.
Sletters is available now on the App Store for free, with in-app purchases offered for additional swaps and ad removal. It’s compatible with iPhone, iPod touch, and iPad, and it comes with an iMessage sticker pack featuring its colorful characters.
In time for the holidays, Sletters has just been updated with a Christmas theme and 15 Christmas levels playable for a limited time.
