Brief Explanations:

The second sentence "Especially when they involve numbers." is a dependent clause and should be connected to the first sentence with a comma instead of a period. Also, the first sentence's period should be a regular period (not a full - width one in some cases, but here the main issue is the sentence structure). So we change the period after "riddles" to a comma and make the second sentence part of the first.

Megatron is very good at solving riddles, especially when they involve numbers.
