Gexx
This is a version of Hexxagon game from 1990.
The player plays with green pieces, the computer plays with blue ones.
Choose a piece to move, then choose an empty cell next to the chosen piece.
If the target cell is adjacent, a new piece will appear there.
If the target cell is one cell away, the piece will move there.
All the enemy pieces next to the occupied cell will change their color to the player's color.
There are three ways to win:
1) Capture all of the enemy pieces
2) When the field is filled, have more pieces than the enemy
3) Lock the enemy so it has no moves left (even if they have more pieces)
Points are awarded for acquiring pieces. The more chips you acquire per move, the more points you get (1 chip - 1 point, 2 - 3 points, 3 - 6 points, etc.). If you capture all of computer's chips or lock them, you'll get additional score. If you win, the final result will be saved. The leaderboard displays the results for the highest difficulty.
