What Makes Othello Dojo Different

Othello Dojo runs a powerful Othello engine. As you play, the position is evaluated in real time, so you see how good each move was right away. Getting feedback while you play builds the habit of noticing what to improve, in the moment.

Move Scoring — Five Ratings

Your move is scored against the engine's read on a five-point scale.

Best The engine's top move, or one just as good. You found the strongest play in the position.
Good Not the very best, but a solid move. Your position is essentially maintained.
OK Not bad, but a better move existed. Watch out for small losses adding up.
Mistake A clearly weakening move. You've handed the initiative to your opponent.
Blunder A critical oversight — handing over a corner, losing many stable discs, a game-deciding error.

Reading the Evaluation Bar

Near the board, an evaluation shows who stands better and by how much — equal, slightly ahead, ahead, winning. The disc count (how many you have now) and the evaluation are two different things. It's common to be behind on discs but ahead on evaluation — that's the depth of Othello.

The Master's Hint

Stuck? Use the master's hint. The engine suggests candidate moves and the idea behind them. Hints and undo each spend one crystal. Choosing when to use them preserves the habit of thinking for yourself first.

💡 How to use it Rather than reaching for the hint immediately, decide where you would play, then compare. Checking whether your read matched sharpens your calculation.

Learn by Undo

The most powerful learning tool is undo (take back a move). When you see a Mistake or Blunder, review it like this:

  1. Note the move where the evaluation dropped. Identify when the position turned.
  2. Undo it. Step back to before the error (spends one crystal).
  3. Try another move. Play what you think "should have been better."
  4. Watch the evaluation change. See how much your new move improved things.
  5. Keep trying until you reach a Best move. Working it out yourself makes it stick.

Difficulty & AUTO Mode

There are three difficulty levels — Beginner, Intermediate, Advanced (strength scales with search depth). Start on Beginner, and move up a level once you win consistently.

AUTO mode lets you watch the engine play itself. Simply observing how a strong player handles corners and mobility grows your feel for good moves. (Hints are unavailable during AUTO.)

Review the Game

When the game ends, use game review to step back through the moves from the start. Hunting for the "turning points" where the evaluation swung most is the fast lane to improvement. Since a single Othello move can shift many squares, learning to spot those turning points is what makes you stronger.

Choosing a Difficulty

There are three levels — Beginner, Intermediate, Advanced — differing in how deep the engine searches. A rough guide:

  • Beginner: learn the rules and why corners matter; enjoy winning first.
  • Intermediate: once you win consistently on Beginner; start weighing mobility and stable discs.
  • Advanced: for testing endgame calculation and parity — even losses teach you via the analysis.

Refilling Crystals (Hints & Undo)

Each hint and each undo spends one crystal. When you run low, watching a short video ad refills crystals (there's a cooldown between views). Don't burn them early — save them for the turning points, where they teach you the most.

Using Game Review — Step by Step

  1. After the game, use game review to step through the moves from the start.
  2. Find the moves where the evaluation swung most (the turning points).
  3. Ask what you'd do differently, and use undo to try another move.
  4. Watch how the evaluation changes, and put into words why the move was weak.

A Practice Routine

A simple loop works best: play one game → find one turning point in review → carry that idea into the next game. Focusing on one fix per game builds steady improvement. If the rules or strategy feel shaky, revisit the Othello guides.
