Hey Mark, looks like you are overthinking this.

For the hasTile method you just need to call the method indexOf and pass in the char value from the method arguments, if it doesn't find the char then it will automatically return the value of negative one.

So, if the indexOf value is greater than or equal to 0, have the method return true, otherwise have the method return false.

The link below should be a bit of help.

indexOf

Thanks.
