This is an ongoing project:
For the game Solver, I will list the scrambled letters, and all of the words I found made from these letters. The bolded letters with a star (*) next to them mean that the words found for these letters won't get you enough points to pass the level, but hopefully there will be less of those. You can contribute by posting any solutions for Solver that are missing from this guide.

TIP: I think it might be useful to find one or two words from the scrambled letters and then use CTRL + F to find the rest of the words you can make. See if this will help you!
