RAUF!en

Description from the publisher:

The game spaces in RAUF!en are arranged in several levels. The bottommost level is the widest one; the more you go up, the fewer spaces there are on every level. The cones always have to be placed on the bottommost level, and there is a maximum of three cones in one space.

Moving to the next higher level is allowed only if all spaces of the current level are occupied — and moving up costs you cones!

There may be cones of only one color on a space. However, they can be captured by opposing cones if those have the majority there.

Crucial for the win is placing and moving your own cones at the right moment.
