Question

it changes one or more letters to spell a different word.

This is because a mutation in the gene (represented by the tiles) changes the sequence of letters, leading to a new word

Answer 1

It sounds like you're describing a word game or puzzle where changing letters in a word creates new words—similar to a genetic mutation causing changes in an organism's traits. This concept could relate to various activities, such as:

1. **Letter Substitution Puzzles**: A game where you change one letter at a time to form a new word. For example, changing "cat" to "bat" by substituting the 'c' with a 'b'.

2. **Word Ladder Games**: Transforming one word into another by changing a single letter at a time, ensuring that each step along the way is a valid word. For instance, "hit" can become "hot" by changing 'i' to 'o', then "hot" can become "dot" by changing 'h' to 'd'.

3. **Anagram Generation**: Although slightly different, rearranging letters (not just changing them) in a word can also create new words. For instance, "listen" can be mutated into "silent".

Is there a specific game or activity you are referring to? Would you like some examples or assistance with a particular word transformation?
