Reversi vs Othello: Understanding the Difference

If you’ve ever searched for information about Reversi, you’ve probably noticed that many people call it “Othello” — and vice versa. Are they the same game? Different games? The answer is nuanced, and understanding the relationship between Reversi and Othello requires a brief journey through gaming history.

The Short Answer

Reversi and Othello are essentially the same game in modern practice. Both are played on an 8×8 board with black and white discs, using the same bracketing-and-flipping mechanic. The differences are primarily historical, legal, and procedural rather than fundamental.

However, there are subtle distinctions worth knowing.

Historical Origins of Reversi

Reversi was invented in England in 1883. The game’s invention is disputed between two men:

  • Lewis Waterman — A Londoner who claimed to have invented the game and published rules for it
  • John Mollett — Who also claimed invention and marketed the game

Both men published versions of the game around the same time, leading to a public dispute. Regardless of who truly invented it, Reversi quickly became a popular parlor game in Victorian England and spread across Europe.

Original Reversi Rules

The original Reversi rules had some differences from modern Othello:

  1. No fixed starting position — Players could place their first few discs more freely in the center area
  2. Starting player choice — Either player could go first (not always Black)
  3. Disc placement — In some versions, the first four moves involved placing discs in the center without flipping

The Birth of Othello

In 1971, Japanese game enthusiast Goro Hasegawa (長谷川五郎) patented and trademarked a game he called Othello. Hasegawa credited his father for teaching him a game similar to Reversi, which he then refined and standardized.

Why “Othello”?

Hasegawa named the game after William Shakespeare’s play “Othello, the Moor of Venice.” The connection is poetic:

  • The play features dramatic conflict between characters associated with black and white
  • The game features black and white discs in constant conflict
  • The dramatic reversals in the play mirror the dramatic reversals on the game board

Hasegawa also coined the famous Othello tagline: “A Minute to Learn, A Lifetime to Master” — one of the most iconic game slogans in history.

Othello’s Standardized Rules

Hasegawa’s Othello established fixed rules:

  1. Standard starting position — D4: White, E4: Black, D5: Black, E5: White (always the same)
  2. Black goes first — Always
  3. Green board — The official Othello board is green (like a Reversi board)
  4. All other rules — Same as Reversi (bracketing, flipping, passing, most discs wins)

The Trademark Situation

“Othello” is a registered trademark, currently owned by Mattel (through its acquisition of various game companies). This has important implications:

  • Physical board games sold as “Othello” are licensed products
  • Other versions of the same game are often sold under the name “Reversi” to avoid trademark issues
  • Online and digital games frequently use “Reversi” or include it as an alternative name
  • The game mechanics themselves are not patented — only the “Othello” brand name is protected

This is why you’ll see many websites and apps use “Reversi” as the primary name while mentioning “also known as Othello.”

Modern Usage

Today, the terms are largely interchangeable in common usage:

  • Tournament players typically use “Othello” because the World Othello Championship (established 1977) uses this name
  • Casual players use either name depending on their region and familiarity
  • In Japan, the game is almost exclusively called “Othello” (オセロ)
  • In Europe, both names are common, with “Reversi” sometimes preferred
  • Online, both names are used to help players find the game regardless of which name they know

World Othello Federation

The World Othello Federation (WOF) was founded in 1977 and has organized annual World Championships since then. The WOF uses Othello rules (standard starting position, Black goes first) as the official competitive standard.

Countries with active Othello federations include Japan, France, the United Kingdom, the United States, and many others. Japan has historically been a powerhouse in competitive Othello, reflecting the game’s deep cultural roots there.

Which Name Should You Use?

Both names are perfectly acceptable, and most people will understand you regardless of which one you choose:

  • Use “Reversi” if you want the historic, public domain name
  • Use “Othello” if you’re referring to competitive/tournament play
  • Use “Reversi (Othello)” if you want to be completely clear — which is what we do at Reversi Pro!

The Bottom Line

Whether you call it Reversi or Othello, you’re playing one of the world’s greatest strategy games. The core experience — the satisfying flip of discs, the battle for corners, the dramatic reversals — is the same regardless of the name. What matters is enjoying the game!
