Secret mode You can find it; 1. Start the 100 Challenge mode 2. Tap the Menu button : On > Off > On > Off > On 3. Tap the Setting button (Right - buttom) Thank you!!
Thanks! I will try it out later! ------ Your secret mode is definitely harder than other mode. I am not familiar with the multiplication that starts with 500, thus taking longer time to play. But it is very challenging! Anyway, are you planning to give $300 to 10 players ($30 each)? That's a huge amount to spend for a contest!
