Discon

Discon is a 1969 uncredited game, published by Doppler Games.

The game is played on a 10x10 board, with four starting corners (the game is for two to four players),

 

There are 96 stones of four colors (16 ivory, 24 pink, 24 blue and 32 purple), plus 24 roofs, six of each labelled 1 to 4,

 

This is a scoring game, where players try to build stacks with as many points as possible. The roofs move like knights and collect different color pieces to make stacks (which can optionally travel with the roofs). There is a complex scoring table for players to account for their points, which is not the most elegant solution...

Here are the official rules:
