The 1 Game

The 1 Game is a 1994 uncredited game, published at The 1 Game.

It is played on a triangular board with three types of pieces,

BGG rules description:

Players take turns removing any number of consecutive balls along a single horizontal line, as long is there is no gap or red ball between them. The removed balls are discarded into the large hole and underneath the slider, which stops them going astray and gets them ready for the next game. The red ball can only be taken on its own. Any row containing red can only be taken up to the red. A blue ball allows players to take up to, or part of, three entire rows radiating from that blue. Other blues in the path are treated as regular silver balls. The player with the last ball loses.

I was able to find the ruleset from the original website (via Wayback Machine, from 5 Dec 1998).
