Our ten day free-game advent calendar bonanza may have come to an end, but we're still going to be using the days up until Christmas to point you in the direction of some games that are always free and are always worth your time.
Have you played Pair Solitaire yet? It's one of those card game variants that you won't believe hasn't been thought up before. I'll try and explain how it works.
52 cards are spread out across the table. You can remove a card if the card two spaces to the left or right is either the same number, or the same suit.
It's a super simple set-up, but this is a smart, tactical game that will have you acting logically and thinking several moves ahead. If you manage to thin the deck down to a few cards, the tension of each card removal becomes palpable.
It's free, it's slick, and it's only 69p to unlock the full game which removes adverts and adds a daily challenge mode and fetching new card backs. Get it here.
