Defender 3 - Hack coins + gems + All level max

The attack and the defense won't grow too much in higher level, but the HP will be sometimes up to 4 million, which is not easy to defeat them in 1 minute.

Also, it's VERY VERY VERY hard to gain the "Dragon's Treasure". Because it only refresh down 50 levels every week. Besides playing Arena mode, I watch ads to get crystals and buy "Dragon's Treasure" in the shop.
