Spiral

I played in solitary variant and I can only give a rough opinion. but the game looks very interesting. it takes a lot of planning and strategy to win against the virtual opponent. it's a brain burn. upgrade: played again today. i didn't think you could win against your virtual opponent. instead i won 2 out of 3 games. it takes a lot of programming. that's why i raise my vote. this is a game i recommend to those who like solitaires on a grid, or similar.
