Rotation & Reversal Codes
Today's big idea
Same letters, new order
Read it backwards, or hop the first letter to the end.
How it works
👀 What's going on?
In some codes the letters do not change at all — they just swap places. Read DOG backwards and you get GOD: the very same three letters, stood in a new order. Rotation and reversal codes are all about the ORDER.
💡 Here's the trick
A reversal code writes the word backwards (CAR → RAC). A rotation code moves a letter round — the first letter jumps to the end (CAT → ATC). The letters stay the same; only their order changes. Spot how the example moved, then move the new word the very same way.
- 1.Look at the example: which letters moved, and where to?
- 2.If it read backwards, write your word backwards too.
- 3.If the first letter hopped to the end, hop your word's first letter to the end too.
✍️ Try it
- 1.BAT → TAB, so DOG → ?
- 2.CAT → ATC, so SUN → ? The first is backwards, so DOG becomes GOD. The second moves the front letter to the end, so SUN becomes UNS.
⚠️ Watch out
The letters never change — only their order. If you see a brand-new letter in an answer, it must be wrong. Check the example again to be sure you moved the letters the same way.

⚡ Time to play!
The letters stay the same — only their order changes. Spot how the example moved, then move the new word the same way.

✅ VERIFICATION
Backwards code: TOP → POT. Using the same rule, code the word BUS.
