Neon Othello

Yes — Othello is the trademarked name for the most popular Reversi variant, and this game follows it: an 8x8 board, the classic diagonal start, and the rule that every move must flip at least one enemy disc.

Yes — pick Easy, Medium or Hard. Easy grabs the biggest flips, Medium looks three moves ahead, and Hard searches five moves deep with a corner-weighted position table. Every AI move is computed in under a second, entirely in your browser.

You pass automatically — the board tells both players when it happens — and your opponent keeps playing. The game only ends when the board is full or neither side can move; then the player with more discs wins.

Yes — 2P mode is pass-and-play on the same screen, no account needed. There is also a Daily challenge: one seeded AI level, color assignment and opening per calendar day, identical for everyone worldwide.
