Sabostack

About this game

Sabostack is a fast, competitive 1v1 block-puzzle duel with a twist.

Stack falling blocks and clear lines to charge up energy. Spend it on attacks that disrupt your opponent, or save it for a bigger combo later. Knowing when to strike matters as much as how well you stack.

How it works:
- Move and rotate falling blocks to complete and clear lines.
- Each cleared line fills your energy bar.
- Use energy to send attacks to your rival.
- The player who survives longer wins.

Attacks:
- Blindness: hides the opponent's board for a moment.
- Inverted Controls: left and right are swapped.
- No Rotate: pieces can't be rotated.
- Auto Rotate: the piece turns on its own.
- Strange Piece: an awkward shape that is hard to place.
- Field Shift, Flip and Side Wind: move, mirror and push the opponent's view.

Ways to play:
- Quick Match: find a random opponent in seconds, or play a bot if no one is available.
- Private rooms: create a room and invite a friend with a link.
- Practice: train against a bot.

Fair play:
Attacks are earned only by clearing lines. There are no paid boosts or stronger attacks for money. Any future purchases are cosmetic only.
