The Climbers / Die Aufsteiger is an easy-to-learn, all-wooden, 3D strategy game with beautiful components, which include 35 colorful blocks of different sizes, a climber pawn for each player, a blocking stone for each player, and a short and a long ladder for each player. Starting with all the blocks in a random tower, players move a block and then climb up the tower gradually -- without ladders for small steps up, and with ladders for larger climbs. Blocking stones keep the block in place and unoccupied for one round, but you can only use your blocking stones and each ladder once during the game. The winner is whoever gets to the highest point first when no one can go higher for one round. You can only climb onto surfaces that are the same color as your climber or gray (a neutral color any climbers can use). Alternate rules allow for simultaneous movement and using ladders as bridges.
