Stacktoe: Angels vs Devils

Stacktoe is tic-tac-toe with a twist: bigger pieces cover smaller ones. Angels and devils each have two small, two medium and two large pieces. On your turn, place a new piece or move one of yours that is already on the board. A piece can cover any smaller piece, yours or your opponent's, and take its square. Line up three of your pieces across, down or diagonally to win. Covered pieces stay hidden, so remember what is underneath. Lift a piece carelessly and you may uncover your opponent's line and lose on the spot. • Two players face to face on one iPhone or iPad, or VS Bot at Easy, Normal and Hard • Drag or tap to play • Learn in a minute with the How to Play guide • Undo a move by watching a short ad • Your game is saved automatically — continue any time • Light and dark appearance • Free with ads; a one-time Remove Ads purchase turns them off • English and Traditional Chinese
