Othello Five is a fresh take on the classic Othello board game where the standard rules get a game-changing twist: instead of just controlling the most pieces, you win by lining up 5 consecutive stones or eliminating your opponent's pieces entirely. You still flip enemy stones by trapping them between yours, but every move carries extra weight when a single well-placed stone can trigger a five-in-a-row victory out of nowhere.

The game offers three AI difficulty levels — Easy for newcomers learning the flip mechanics, Normal for casual players who want a real back-and-forth, and Hard for anyone who wants to think several moves ahead. One of the coolest features is watching the AI's thinking process in real time, so you can actually learn from how it evaluates positions. Smooth animations keep the board readable, and built-in stat tracking lets you see how your win rate improves over time. You can also switch to two-player mode and go head-to-head with a friend on the same screen.

This game is a perfect pick for fans of free online strategy board games, classic reversi variations, and two-player browser games that don't need any downloads or sign-ups. Whether you're killing five minutes or grinding ranked matches against Hard AI, Othello Five delivers a satisfying blend of casual play and tactical depth that fans of free online puzzle and board games will keep coming back to.
