At its heart Diffrentia is a simple, old-fashioned-style card game that is easy to pick up and gives you strategic options, plus a weekly goal - to win for your chosen clan.

Choose your favourite clan to battle for out of Cat, Fox, Falcon, and Dragon then gain the most points before 6pm every Sunday to win.

Receive commentary after each game ranging from encouraging and uplifting to thinly-veiled (and not so thinly-veiled) sarcasm.

Return to the menu at any time to gain a precise run-down of how many points each clan has in the weekly battle.
