Often on online multiplayer apps of Scrabble and Words With Friends, you have unlimited time to make your move. As a result, most people use anagram solvers to "cheat". However, because this "cheating" is so common, it's been the norm and possibly may need to use it to be competitive in the app.
What additional strategies should you use given that you have an anagram solver tool? I would think aiming to get "Bingo" more often, playing 7 letters to get 50 bonus points.
If both players play the same number of tiles, then they will on average play the same number of points. By playing your tiles on the multipliers of the board, you can increase the number of points you get to greater heights than your opponent, while denying your opponent the ability to use those same multipliers
It is only possible to play on squares that are accessible to the existing tiles on the board. Your opponent will play immediately after you - they have an opportunity to use any multipliers that you've uncovered before you get a chance. Deny them this opportunity whenever possible!
The number of tiles you draw each round is dependent on the number of tiles you play. So if you play exclusively 6 tile words while your opponent plays only 3 tile words, then you will end up drawing twice as many tiles than your opponent, which means you will have access to twice as many points. This is in addition to the massive point bonus achieved for using all 7 tiles, which should be taken advantage of whenever possible.
A multiplier space is only as good as the tile you place on it. A 3x letter multiplier is only worth 2 extra points if you play an 'S' on it. But if you play a 'Z' on it, it's worth 20 extra points.
The points you get are more than just the tiles in your hand - it's also the tiles already on the board that are part of your word. That means you should look for ways to use the high value letters already on the board in order to add their points to your own, and to prevent your opponent from using them.
Very frequently, these strategies will be in conflict with each other. It is up to you to weigh them and figure out which one is to your maximum benefit at any given point in the game.
