Here is a helpful tip for the memory game.
Memory Game Tip
Grabbing a piece of paper and writing down what you see is a valid way of playing the memory game, and should be encouraged to get the most out of the game, but…
Steam got an overhaul recently and they now have a notes feature that could be useful in any game that has a lot of things to keep track of.
They give you the ability to type things down and pin them on the screen.
Instead of wasting paper, use this feature instead in the memory game! It has the added benefit of being on the screen instead of looking at your paper notes every 5 seconds. Also, you can set the opacity to you liking once it is pinned if the notes end up blocking your screen.
