How OpGlyph works (60 seconds)

Operators + feedback → quick “aha”.

1) Fill the blanks

You get digits with “?” operator slots and a target. Choose operators: + − × ÷.

No parentheses. Compute strictly left-to-right.

2) Commit with Enter

You can place operators freely, but nothing counts until you press Enter. Enter uses up one try and shows feedback for your operators.

6 tries operators are the “guess” digits + target stay fixed

3) Use feedback

Each operator gets Wordle-style feedback:

🟩 right operator in the right slot 🟨 operator exists but wrong slot ⬛ operator not in the solution

Two quick examples

Example A (Easy)

Digits: 8 ? 2 ? 5 = 11
Slots: 2 operators

Try: × then + Try: + then −

Press Enter to see which operators are correct and where.

Example B (Hard)

Digits: 9 ? 3 ? 2 ? 8 ? 4 = 20
Slots: 4 operators

Use one × early Then steer with + / − ÷ can “tune”

Watch for ⬛ operators you can eliminate completely.

Play Easy Try Hard

Tip: it’s faster when you treat operators like a Wordle guess.
