Example 1

Encrypted Word: LFGNOEIL
Screens (Top to bottom): 128/0 123/1 578/1 456/1
Using Encrypt Rules

LFGNOEIL + 456 → LFG---IL, NOE + 1 → ENO + LFG---IL → LFGENOIL
LFGENOIL + 578 → LFGE-O--, NIL + 1 → LNI + LFGE-O-- → LFGELONI
LFGELONI + 123 → ---ELONI, LFG + 1 → GLF + ---ELONI → GLFELONI
GLFELONI + 128 → --FELON-, GLI + 0 → LIG + --FELON- → LIFELONG

Decrypted Word: LIFELONG

Example 2

Encrypted Word: ACEHT
Screens (Top to bottom): 123/0 135/0 124/1 145/0
Using Decrypt Rules

ACEHT + 123 → ---HT, ACE + 0 → EAC + ---HT → EACHT
EACHT + 135 → -A-H-, ECT + 0 → TEC + -A-H- → TAEHC
TAEHC + 124 → --E-C, TAH + 1 → AHT + --E-C → AHETC
AHETC + 145 → -HE--, ATC + 0 → CAT + -HE-- → CHEAT

Decrypted Word: CHEAT
