Pivot Disks

Original 8×8 disc strategy. Place a legal disc and flip all directly bracketed opposing lines. Blue starts; sides without moves pass automatically. When neither side can move, more occupied discs wins; equal counts draw.

One human faces a bounded corner/mobility-aware strategy bot. Exactly two local humans take turns; exactly two signed-in online humans share a replay-validated public board. Online turns have a sixty-second deadline; results are casual host-managed and unverified. No reconnect or host migration.

Select and inspect legal flips before separate placement. Native responsive scene, bounded artwork, cursor zoom, original synthesis, English/Portuguese Help, solo Undo and rematch. Portrait preferred; landscape supported.

• Touch/mouse: tap a cell to preview, then separate Place below the board
• Large cursor arrows and zoom help dense boards; Undo solo only
• M mute; Escape pause solo/local; online Help stays live
