Borderline is a fast, deep strategy game played on a simple 5x5 board — easy to learn, hard to master.
Take turns placing your pieces on the board. Line them up along the board's edges, or form a tight 2x2 square, and you'll capture your opponent's pieces. Once every space is filled, the real battle begins: maneuver your remaining pieces one step at a time, keep forming patterns, and force your opponent down to their last two pieces to win.
FEATURES
* Single Player mode with three AI difficulty levels — Easy, Medium, and Hard
* Two Player pass-and-play mode for head-to-head games on one device
* Clean, tactile wood-board design
* Win/loss tracking, kept entirely on your device
* Completely free — supported by non-personalized ads only. We don't track you, and we don't need to: no account, no sign-in, no personal data collected.
Whether you're looking for a quick game on your commute or a deep strategy challenge against a smart AI opponent, Borderline is built to be picked up in seconds and hard to put down.
