The Kasus was the last Tura machine with approval by authorities. You've seen right, it has 30 Stop positions, but only the white space between the geometric symbols is profit zone.
-Insert coin, pull handle
-Start machine reels running by push left brake button
-Hard push on brake buttons stops reels
-After stop reels you have to "shift" reels with soft touch on brake buttons to a "profit combination"
Running time (and shifting possible) is from left to right reel: 2 1/2, 3 1/2, 4 1/2 seconds.
So you have to play against the clockwork inside.

After war no one wants to have machines with Kasus system. They were all wrecked, in most cases to build up "normal" machines. In some cases Kasus parts appear in "normal" Tura machines, like the one wheel with gear inside at first machine in this thread.
At the moment I prepare the Kasus for Automateum-Convention this month. If machine is running I post you a video link.
