How does the ranking system work?

Your rating starts at 1000. Win matches to gain rating points, lose to drop points. The amount you gain or lose depends on your opponent's rating. Beating higher-rated players gives more points!

Can I play against bots?

Yes! When creating a match, you can choose to play against AI opponents of varying difficulty levels. Bot matches still affect your rating, but with a reduced multiplier (0.6x).

What's the difference between ranked and casual?

Ranked matches affect your rating and appear on the leaderboard. Casual matches are just for fun and don't impact your rating.

Can I rematch my opponent?

Yes! After a match ends, you can request a rematch. If your opponent accepts, you'll start a new game immediately with the same opponent.

How does sliding mode keep the game from being a draw?

In sliding mode, pieces automatically disappear after 6 total moves (3 per player). This constant movement prevents board stalemates and keeps the game dynamic.

Strategy Tips

Elevate your game with these strategic insights from expert players.

Control the Center

The center cell (middle square) is the most valuable position. It's part of 4 different winning lines.

If possible, take the center early in the game.

Create Multiple Threats

Set up two winning opportunities at once. Your opponent can only block one!

Look for moves that create two possible wins.

Block Your Opponent

Always check if your opponent is one move away from winning. Block them before pursuing your own win.

Defense is as important as offense.

Corner Strategy

Corner cells are powerful. They're part of 3 winning lines each (one row, one column, one diagonal).

Corners give you more ways to build a threat.

Think Ahead (Sliding Mode)

In sliding mode, remember which of your pieces will disappear next. Don't rely on pieces that are about to vanish!

Plan your next 2–3 moves, not just the next one.

Force Mistakes

Put pressure on your opponent by creating complex situations where they might overlook a threat.

The best players make simple moves look threatening.

Pro Tip
Great players don't just react — they plan ahead, control space, and create multiple threats!
