How to play Yyoki spot-the-difference
Yyoki is a browser-based real-time puzzle game where players compare two images and find the changed areas. Create a room, share the code, and friends or family can join the same round from their own devices.

1. Create or join a room
New visitors can start as guests. The host chooses the photo count, time limit, player limit, and item mode before sharing the room code.
- Quick join finds an available public room automatically.
- Code join is useful when a friend has already created a room.
- Solo mode lets you practice and measure your record without waiting for others.
2. Get ready in the waiting room
The waiting room shows participants, ready status, and the host. When everyone is ready, the host can start the game.
- The host can review room settings before starting.
- Players use ready status to show they can begin.
- Mobile and desktop players can join the same room.
3. Compare and tap differences
When the round starts, compare the two images. Tap or click a changed area and the server checks the answer area before updating the score.
- Found differences are shared with all players.
- Very rapid repeated clicks may be limited to prevent answer spam.
- If an area looks small, compare one region at a time instead of tapping randomly.
4. Review results
After the round, review rankings, scores, found counts, and solo records. If your representative yokai is a base form, it can gain evolution EXP from completed games.
- Multiplayer ranking depends on score and finding order.
- Solo mode focuses on completion time.
- Play again returns the room to the next-round flow.
5. Practical finding tips
A consistent scan pattern is more reliable than random tapping. Start with object edges, shadows, background borders, and small decorations.
- Scan from top-left to bottom-right in a zigzag path.
- Compare color, brightness, and shadow length changes.
- If an answer feels uncertain, check two or three nearby details first.
6. Choose the right mode
Solo mode is best for personal records, while multiplayer rooms are best when friends or family want to compete in the same round.
- Try one solo round first, then create a multiplayer room.
- For couples or long-distance play, use 2 players, 5 photos, and 3 minutes.
- For parties, turn items off for the first round and enable them after everyone learns the flow.
Recommended first settings
Start with 5 photos, a 3-minute limit, and item mode off. After players learn the rules, increase the photo count or enable items for a more competitive round.
