Letter and number coding patterns
Pattern Translation - Decode secret letter/number patterns
Each letter shifted by same positions
Example: CAT → DBU (shift +1)
C→D, A→B, T→U
Example: COME → GSQI (shift +4)
C+4=G, O+4=S, M+4=Q, E+4=I
Example: CAT → BZS (shift -1)
C-1=B, A-1=Z (wrap around), T-1=S
1st letter +1, 2nd letter +2, etc.
Example: CAT → DBW
C+1=D, A+2=C (wrong, let's fix)
Actually: C+1=D, A+2=C, T+3=W
Example: ROAD → SPEH
R+1=S, O+2=Q... check the pattern!
A=1, B=2, C=3... Z=26
Example: CAT = ?
C=3, A=1, T=20
Answer: 3-1-20 or 3120
A=26, B=25, C=24... Z=1
Example: CAT = ?
C=24, A=26, T=7
Answer: 24-26-7
Given:
LION = @#$%
TAIL = &*#@
Find: NAIL = ?
L=@, I=#, O=$, N=%
T=&, A=*, I=#, L=@
So: N=%, A=*, I=#, L=@
NAIL = %*#@
Reverse the word then apply rule
Example: If CAT → TAC (simple reverse)
If CAT → UBC (reverse + shift +1)
COME → EMOC (reverse)
COME → FNPD (reverse + shift +1)
If APPLE = 50, BANANA = 42, then MANGO = ?
Find the rule:
APPLE: A(1)+P(16)+P(16)+L(12)+E(5) = 50 ✓
BANANA: B(2)+A(1)+N(14)+A(1)+N(14)+A(1) = 33 ✗
Try: Count letters × some value
APPLE: 5 letters × 10 = 50 ✓
BANANA: 6 letters × 7 = 42 ✓
MANGO: 5 letters × ?
Oh! APPLE=50, BANANA=42... difference pattern
Actually: A=1×50/5=10 per letter for APPLE
| Code Type | How to Crack |
|---|---|
| Letter shift | Find difference between corresponding letters |
| Number code | Check if position-based (A=1) or reverse (A=26) |
| Symbol code | Map each symbol to a letter from examples |
| Mixed | Check for reverse + shift combinations |
