Solitaire a real favourite of mine. Used to play it lots back in the day. At only 90mm circumference and 30mm height you can carry easily and play Solitaire anywhere. Remove the middle peg then just play like draughts/checkers . jump one then Remove the jumped piece. Keep going... The mission is to be left with just one piece.. Golden mission is to be left with only one piece in the centre.... Not easy...Not for small children as can choke on the pegs. I designed and 3d printed this one... The top has the name SOLITAIRE printed on it. Only open this way up so the pieces don't fall out 🙂. Checkout sellers other items for amazing items 👌 🙌 😍
