"Late last year when we were first introduced to Peter Capaldi as the next regeneration of the Doctor we were also introduced to Doctor Who: Legacy, a companion collecting puzzle game from Tiny Rebel Games. It's come quite a long way since then.
Like the popular Puzzle and Dragons, Doctor Who: Legacy is a game about collecting color-coded creatures and using them participate in match-puzzle battles. Unlike Puzzle and Dragons, Doctor Who: Legacy isn't all about paying for rare monsters. There are no ads in the game, just a simple, understated store, politely clearing its throat when you wander over and mentioning that, should you be interested, there are things for sale. It's one of the very best examples of free-to-play."
