HOW TO PLAY
NUMBER POSITION
A logic puzzle where you crack a secret 4-digit code.
Think. Guess. Crack the vault.
The Objective
Each game hides a secret 4-digit code. Every digit is unique (0-9, no repeats). Your job is to figure out the code using logic and deduction.
In solo mode, choose between a 10-turn challenge or infinite turns. In multiplayer, race your opponent to crack their code first.
How to Guess
Tap digits on the numpad to fill the 4 slots. Each digit can only be used once per guess. Press Submit when ready.

All 4 digits match (Num=4), but only 4 is in the right position (Pos=1). The others (1, 2, 8) are in the code but in the wrong spots.
Strategy Tips
1
Start wide. Use digits that cover a broad range (like 1-2-3-4 or 5-6-7-8) to quickly identify which digits are in the code.
2
Num=0 means elimination. If Num is 0, none of those digits are in the code. Never use them again.
3
Num > Pos means reposition. Some digits are correct but in the wrong spots. Shuffle them around.
4
Hold to disable. Long-press any digit to mark it as eliminated. Disabled digits show a strikethrough and can't be entered.
