We've owned this game for a while and played many times with our kids (age 5, 9 and 11) bought again recently from Athena games for cousins for Christmas.
Box says 8 plus but the 5 year old has grasped it well and plays by herself now rather than in a team with an adult. We're fussy about our board games, they need to have replayability, have lots of interesting elements and be fun for adults and children - this ticks all the boxes. It has some elements of strategy and some elements of luck. A perfect pre-cursor to games like Catan, highly recommend.
