Get ready for a challenge that's wickedly wonderful and totally terrific!
Horrid Henry needs your help! Mum’s locked away his Killer Boy Rats tickets and he needs you to get them back so he can get to the concert on time! Dad says that if you solve the eight puzzles, each one will give you a bit of the passcode that you need to get to the tickets... the question is, are you up to the challenge?!
The game includes 7 escape room style puzzles to solve, which together create a passcode.
Break into the online vault with the passcode and reveal the secret message hidden within.
Clues are available online so no one will get stuck!
