Abstract Games
These are some abstract games programmed in javascript for solo
play.
VennDoku
Figure out the size of regions in Venn diagrams. This comes
in two sizes, VennDoku2 and VennDoku3.
Bulls & Cows
The old logic chestnut, perhaps
better known under the commercial name of Mastermind.
Tic-Tac-Toe
Everybody's first abstract game.
Terni Lapilli
The ancient Roman form of
tic-tac-toe - a little bit better than the modern variety.
Invaderz
A variant on Hasami Shogi.
Oust
A game designed by Mark Steere. I
might have called it Zug-Zwang-Zwang.
Four-in-a-Row
Another classic, in two sizes: 5x5 and 6x6.
Gerrymander
A game inspired by the political
shenanigans of the same name.
