## What is Last Control: Decode?

Last Control: Decode is a daily codebreaking game presented as an intercepted transmission. Each round shows a line encrypted with a Caesar shift and asks you to choose the original English sentence from the answers on screen. A complete daily puzzle contains three rounds, with no timer pushing you to answer.

The shared challenge changes at midnight UTC. Its short format makes it a compact introduction to substitution ciphers without requiring a full cryptogram worksheet.

## Understanding a Caesar shift

A Caesar cipher moves every letter by the same number of places through the alphabet, wrapping around after Z. With a shift of three, A becomes D and B becomes E. To decode the message, move the letters back by the corresponding amount.

As an illustrative example, KHOOR decodes to HELLO by shifting each letter back three places. Once a possible shift works for one word, it must also work for the rest of that round's sentence. Word lengths and repeated letters give you useful checks.

## How to solve the three rounds

1. Select Begin to open the daily transmission.
2. Compare the encrypted line with the proposed English sentences.
3. Test a short word or a repeated letter to identify a plausible alphabet shift.
4. Apply that same shift to another part of the line before selecting an answer.
5. Continue through the remaining rounds and review the daily result.

## Codebreaking tips

A three-letter word is often a convenient starting point, but do not assume it must be THE. Verify the mapping elsewhere before committing. If one candidate has a different pattern of word lengths, eliminate it before doing letter-by-letter arithmetic.

Treat each new round as a fresh cipher check. The important skill is recognizing a consistent substitution across the full sentence, rather than remembering the setting from the previous round.
