Reversi with a daily rule

한국어

Trap the opponent's discs between yours and everything in between turns to your color. That is plain Reversi, and what makes this board different is that you choose one extra rule for the day and lay it on top.

Three of the 6 candidate rules are drawn for the day. You ban one and pick one. Everyone gets the same three on the same day, so what you ban and what you pick is where the skill is.

No account, no loot boxes. Judging and your record are always free.

How this board works

There is no randomness. The candidates are set by the date, and the opponent always plays the same moves on the same board. A lost game is not bad luck but the wrong order of moves, so memorizing the board makes you better.

Flipping the most discs is not the best move. That is an old property of Reversi, and in our own simulation the side that only counted flips lost under all six rules.

A rule never kills the board. Whatever rule is on top, you never run out of places to play. If narrowing would leave nothing, we made it stop narrowing.

We do not count days in a row. We say nothing about the days you did not come.
