Be cautious on leveling 3 and 4 bed monsters above level 10. At that point you start to get diminishing returns as the amount of coins needed to bake food and feed them exceeds what you will get in return. This is especially true with the 1 and 2 bed monsters. Some monsters take several months to earn back the amount of coins you spend to get them to level 15.

I know everyone thinks 4 bed monsters generate the most coins, but the reality is that 3 bed monsters offer the greatest return on investment if you play the game a few times a day. If you only collect coins once or twice a day, then the 4 bed monsters are the way to go.

I agree, leveling up the castle on the existing islands and getting as many 3 bed monsters as possible is far more important than buying the next island.

The only advantage to buying a new island is to be able to place a mine on it first thing. Otherwise, far more productive to increase castle to maximum beds and full up the island with monsters before buying the next island.

Leveling 3 and 4 bed monsters to level 10 or 11 (leaving 1 and 2 bed monsters on level 4) and filling up the existing island to near maximum before moving on to next island will get you further faster than trying to buy as many islands as possible before you are ready.

Just my opinion.
