LetterGrid takes the word-search idea and turns it into a fight over territory. Punginsoft's multiplayer, turn-based game is inspired by Wordbase: you play on a board of letters, and the tiles you use in your words become yours. The publisher likens it to chess with letters instead of pieces, which is a fair hint that the vocabulary is only half the skill.
You find words by connecting letters on the grid, and the tiles in your word turn into your territory. Your opponent does the same, so the board becomes a contest for space. Each word you choose also changes what your opponent can do next, which means a clever short word can matter more than an impressive long one.
Invasion asks you to build a chain of words from your border to your opponent's border, with every word starting from a tile you already own. Territory asks you to occupy a set number of tiles before your opponent does, using words that include at least one of your existing tiles. In both modes you can expand, steal tiles and even cut off sections of the other player's territory.
The listing mentions interactive tutorials, matches against people or AI, an Elo-based player rating, leaderboards for recent wins and overall rating, detailed statistics with progress graphs and 11 languages. An Elo rating moves according to the strength of the opponents you beat or lose to, which tends to produce fairer matchups over time.
Before you play a word, ask what your opponent can do in reply. Do not always choose the longest word; a shorter word that blocks a route can be worth more. In Invasion, advance toward the opponent's border while keeping your chain safe from being cut. In Territory, claim large areas first and use leftover moves to steal tiles. Learn useful word patterns, including words with uncommon letters, because they open options others miss. Practise against the AI to learn the tutorials and test ideas without risking your rating.
Because the game is turn-based, you can make moves at your own pace, which suits people who like asynchronous play. If you want fast real-time action or solo puzzles, it will not be the best fit.
Multiplayer means other people, so be polite and avoid sharing personal information. Check the store page for current advertising or purchase information.
