A Matryoshka doll is, of course, a set of Russian nesting dolls. This little card game is about re-assembling sets of these dolls that have been separated.
Players start with a hand of random cards. They offer one to sell each round, allowing the other players to make an offer in trade, and then exhibit their collection. After several rounds, the player who's put together the most valuable set will win.
It's a nice little game with some tactical niceties and brightly coloured cards.
For 3-5 players, aged 8+, playing time 20 minutes: £9.50 (£7.92 without tax outside the EU)
