I like this game, which is a bit like Boggle, in that you track through the letters to make words. The difference is that every single letter is used (and once there are no more words that use that letter it's greyed out and at the end all the letters are greyed out). That seems like magic to me! :)
Drag a finger or mouse cursor through letters to form a word which gives you points. Playable on web or phone browser, not sure if there's an actual app yet despite the web address.
Is fun :) New one every day at 11am UK time. Most are 4x4 grids but sometimes there's a variation: https://squaredle.app/
The jigsaw icon top left lets you toggle between the main game and 'Squaredle Express' which is a 3x3 grid. The icon on the right lets you turn the board round.
Happy Squaredling
