Siege Duel is a sharp, fast tactical board game: move your piece, drop a wall, and squeeze your opponent until they have nowhere left to go. Easy to learn in 30 seconds, deep enough to keep you thinking for hours. Every turn you do two things — move to a neighboring square, then place a permanent obstacle anywhere on the board. Slowly the open space shrinks. The first player with no legal move is trapped and loses. FEATURES • Play offline against a smart AI or a friend on the same device — no internet needed for offline modes • Online ranked mode — get matched with players around the world and climb the leaderboard (optional, needs a connection) • No ads — ever • Optional cosmetic coins, board and piece themes — earn them by playing, or buy a pack to support the game • Smart AI with 3 levels (Easy, Medium, Hard) powered by a real search engine • 3 board sizes: 6Ɨ6, 8Ɨ8 and 10Ɨ10 • Warm, hand-crafted board-game look with a Knight vs Mage theme • 15 languages • Quick matches, instant restart, satisfying sounds and haptics HOW TO PLAY 1. Each player places their first piece on any empty square. 2. On your turn, move your piece to one of the 8 neighboring squares. 3. Then drop one obstacle on any empty square. 4. Corner your rival so they cannot move — and win. A pure strategy duel of territory and timing. Think ahead, build your walls, and spring the trap.

Margin is a pursuit puzzle you win with your head, not your thumbs. Every level is a small board. You move one square at a time. So do the hunters — and they always take the step that brings them closest to you. That is the whole rule, and it is also the whole trick: because you know exactly what they will do, you can decide where they end up. An arrow above each hunter shows the step it is about to take. Read the arrows, and a level stops being a chase and becomes a plan: pull the pack one way, slip through the gap they leave, walk out through the exit. • Three tiers: Easy, Medium and Hard. Each one puts more hunters on the board and less room between them. • Daily Board: one board for everyone, every day, separately for Medium and Hard. Solve it to earn 200 points on Medium or 400 on Hard, and claim your spot in the daily ranking. • Challenge a friend: send a board you've won as a link. They play the exact same one, then can watch your game step by step. • 48 titles to earn, plus weekly and all-time leaderboards on Game Center. • Every level is generated and then solved by the game before you ever see it. If it is offered to you, it can be beaten. • Every board shows its minimum move count. Each extra move costs a point (up to 5), so the shortest escape earns the most. • A hint when you are stuck, and a fresh board whenever you want one. • No timers, no lives, no energy to wait for. Think as long as you like. • Plays in portrait, one thumb, anywhere. There is no margin for error. There is exactly one square of it.
