FREE Easter Egg Hunt – Crack the Code

Modified: Apr 10, 2025 · Published: Mar 28, 2022 by Emma Vanstone · This post may contain affiliate links · 7 Comments

Several years ago, we started creating Easter egg hunts with codes as clues to make searching for the eggs take a bit longer. The codes started out very simple ( letters replaced with numbers ) but have become increasingly complex over the years.

I’ve created some free printable easter egg codes to make this year’s Easter egg hunt easier than ever to prepare! Including some with the writing backwards!

Coded Clues – Easter Egg Hunt

These clues have the letters replaced with a number. The key is at the top to make it super simple!

More Easter Egg Hunt Code Ideas

Replace each letter with a number corresponding to its place in the alphabet.

Reverse the Alphabet ( Z becomes A, A becomes Z etc.)

Move each letter one along ( A becomes B )

Move each letter 2 places along ( A becomes C )

Write in invisible ink – lemon juice is great for this.

Write in white crayons on white paper so the children have to find a way to reveal the clue ( colour over the writing with a different colour crayon or water colour paints )

Replace each letter with a symbol

Make a code

Can you think of any more codes?

This activity is a lot of fun and great for improving logic skills.

Frugal Fun for Boys and Girls has a brilliant LEGO coding activity, too!

    This is such an interesting activity which you have shared to develop logical thinking of kids in a fun way. It is so important to involve kids in activities which can teach the basics of coding for kids with the help of games & apps. We at TechyKids Canada make sure that all students are given extensive training of coding skills in a way which not only prepare them for the competitive world but also secures their future. Thanks for sharing this!
