Beat all the castles? It's impossible to defeat the Djinns with their halving ability. Agar is forced to sit and wait for his demise.
Actually, I defeated them today (the Djinns):D
Try placing the dragon in the furthest (left) slot;)
I understand that it's not necessary to kill the AI opponents; you need to "cure Agar" from his bad luck.:)
