Rules
Uisge is a two-player game on a 7x6 board. Each player controls six double-sided pieces (Pawn/King).
Goal
Win by turning all six of your own pieces into Kings (crown side up).
Turn Sequence
- Select one of your pieces.
- Any piece may jump orthogonally over exactly one adjacent piece (own or opponent) into an empty square. The jumping piece flips Pawn/King.
- Kings may also move one step to any adjacent empty square (including diagonals) without flipping.
Connectivity Rule
After every move, all 12 pieces together must remain in one orthogonally connected group.
If a move would split the group, it is illegal and not offered as a selectable action.
In this implementation, if the next player has no legal move, that player loses.
Options
Changes take effect immediately on AI turns and on new games.
