5. Wakugumi Monochrome Puzzle
Remember Polarium? It was a DS launch title, and although it’s quite old, it’s also still very playable. Wakugumi comes from the same team, and is similarly classy. It’s hard to describe, but what you’ll be doing is moving black and white colours around to enclose one colour in a box of another. It sits on the more hardcore side of puzzle games and requires a lot of quick thinking, but it’s compelling nonetheless.
