Pillar checkers, duel

1. A regular checker moves one square diagonally forward; a queen moves any distance diagonally.
2. Capture by jumping — the captured piece goes under your checker to form a tower.
3. A tower moves as one piece and belongs to whoever's checker is on top.
4. Reach the far row to turn a checker into a queen.
5. Win by covering or blocking all of your opponent's pieces.

Pillar checkers, duel plays like classic checkers with one big difference: captured pieces never leave the board. Instead, each captured checker is tucked beneath the checker that captured it, building a tower that moves as a single unit. Whoever owns the top piece owns the tower, and it moves like a regular checker or a queen depending on what sits on top — so capturing an enemy tower can expose pieces underneath and change who controls the rest of it. You win by covering or blocking every enemy piece rather than simply removing them. You can play against the computer, with a friend on one device, or against an opponent online.
