In TILE you score points by making as many words as you can in a 60-second round. Shorter words are worth fewer points and longer words are increasingly valuable; just 1 point for 3-letter words, up to 105 points if you manage to use all 25 tiles on the board. Letter tiles appear in a 5-by-5 grid. As you make words the tiles are consumed and new ones settle down onto the grid.
In solo play you are always playing a new, completely random set of tiles, trying to get the highest score you can, competing against just yourself and the clock. Getting a great score in solo play is a balance between finding long words and finding words quickly.
In daily board play everybody plays the same sequence of tiles for as many 60-second rounds as they like, trying to get the most points out of those same letters as they can. Playing the same board several times exercises your memory for upcoming letters and lets you strategize around word-length over many plays. Every day a new board unlocks and you can play it as many times as you like.
