4 vs Odd Color Out

Go for 1st place or just avoid last — your strategy is your own. ■ Rules ① The basic rules are just like traditional Othello: players take turns placing stones and flip the opponent’s stones when sandwiching them. ② When the board is full, rankings from 1st to 4th are determined by who has the most stones. ③ If you can't make a valid move, you can place a stone on any empty space adjacent to an opponent’s piece. ■ Online Play ・Battle real-time with players around the world! ・Share a room code to easily play with friends. ・If fewer than four players join, CPU players will automatically fill in.

How well can you distinguish between colors? Perhaps you have a special ability. The ability to recognize colors varies from person to person, and very few people can accurately distinguish subtle differences in colors. Only individuals with exceptional color vision can do so. You may be one of them. Would you like to test your skills and find out? I have created a game that allows you to test your color recognition skills and see how well you perform. You can also check your score on the global rankings and play with family and friends with the multiplayer feature. Maybe someone with special abilities is close you. Why not try playing together? This game blends elements of both "color vision tests" or "color blind tests" as well as "odd one out" games. - How to play Find the one square that is slightly different in color from the others and touch it.
