Welcome to Friday, everyone. The beginning of the new year tends to be slow, but thankfully we have some solid sales today, including some excellent standouts. First up is Old Man’s Journey, a gorgeous adventure game that also offers a heartfelt story. Next is Hexologic, a Sudoku-like game that uses hexagons instead of squares. Last but not least is ELOH, a relaxing puzzle game that offers a compelling rhythm mechanic. As always, I’ve highlighted all of the interesting titles in bold in order to make discovery easier. So without further ado, here are the best temporarily free and on-sale apps and games for the end of the week.
