"H. G. Wells playing a wargame with the rules of Little Wars. Wells is using a piece of string cut to a set length of the distance his soldiers can move. An umpire sits in a chair with his stopwatch timing Wells. Wells' opponent waits for his turn to move and fire his cannon at Wells' soldiers." From Wikipedia on H.G.Wells
Players "eyeball" their shots and then call out the degree heading they wish to shoot at. Strings are run through the center of the 4" x 4" counters and pulled taught along the bearing announced by the player. If the string crosses an enemy ship diagram, it's a hit. Very fun game!
"Each player guides his team of 3 small climbers up the two foot tall, steep mountain. They place spikes which, along with ledges, are used by climbers to keep hold and scale the mountain. The team's climbers are joined to each other by "rope" (string). Dexterity is important, as players use a rod to hook and lift climbers, one at a time, onto the spikes and ledges. The winner is the first player to get one climber to reach the summit."
