So... How do you get 154 medals?
#1:
Trophy section: "five" pages with "six" challenges each.
"Five" times "six" equals "thirty" (+30).
#2:
"Like us" section: you can get "four" (+4).
#3:
"Premium Content" you get "ten" (+10).
#4:
Each mission has "four" challenges. Each challenge awards you a medal.
Each mission has "three" difficulties. Each one awards you a medal.
That tells us that each mission has "seven" (+7) possible medals.
#4.1:
First country has "four" missions. "Seven" times "four" equals "twenty eight" (+28).
#4.2:
Second country has "four" missions. "Seven" times "four" equals "twenty eight" (+28).
#4.3:
Third country has "three" missions. "Seven" times "three" equals "twenty one" (+21).
#4.4:
Fourth country has "four" missions. "Seven" times "four" equals "twenty eight" (+28).
Now the math:
#1+#2+#3+#4.1+#4.2+#4.3+#4.4 = X
30+4+10+28+28+21+28 = 149
154-149 = 5
5=?
