Taking the changing rules concept of something like Fluxx (but with a greater reliance on strategy than pure luck) and applying it to the simple colours and numbers design of Uno, Red7 is a very easy game to pick up and play with a surprising amount of depth. Each round, players can add to the set of cards they have in play or change the current rules based on each card’s colour – or both. Failing to achieve the ‘winning’ rules in play means elimination, simple as that. Red7 can be explained in about 30 seconds and played in as little as five minutes, and can be fittingly picked up for as little as £7 – a bargain, given that you’ll want to play again and again.
