Monsterwood is an area that appears for players after having played for 20 days. It allows players to watch ads (most of which are typically 30 seconds long) for rewards: gems, gold, food, relic chests, monster cells, monsters, maze coins, and more. Social Point regularly offers "happy hours" where players can view more ads and earn greater rewards.
After watching the first 5 ads for the day, there will be a roulette wheel that will allow you to win prizes such as gems and rune chests. A second roulette can be spun after watching 15 ads.
