Feeding your monster at Tribal Island, although Shards are more efficient.
The Monsters themselves are the main source of Coins. Monsters placed on most islands earn Coins in proportion to their number of elements, level, and happiness. In order to earn Coins, the monster must be visible on the island (i.e., not inside of a Hotel), but they can be muted (sleeping). A monster can earn coins up to a maximum number which is proportional to its level but is not affected by its happiness. When the monster's coin count reaches 75% of its maximum, a balloon with a coin icon appears over the monster, as a hint to the player to collect the coins. See individual monsters' pages for specific earning rates and coin limits.
Coins may be also purchased with actual money in the Market, or Diamonds can be exchanged for Coins.
Monsters can be sold for Coins, except on Gold Island (where there is no market), Tribal Island (where the monsters can only be taken away, not sold), and Ethereal Island (where they can be sold for Shards instead; see below). A monster can be sold at the time it is ready to hatch and be placed on the island, or any time after it has been placed. A monster's price is a constant, and does not change with the monster's level. See individual monster pages for specific sale prices.
All Decorations and most Structures can be sold back at any time after they have been placed on an island. The sell-back rate is three quarters of the purchase price. There is no depreciation on older items.
Some of the Goals give rewards of coins, which vary with the difficulty of the Goal. Currently the largest Coin reward is 20 million coins for the goal of buying and placing a Tub Fountain.
The daily Scratch Ticket available from the Castle has Coin prizes of various amounts. The most common award is around 100 coins, as it may scale up according to the player's Experience.
Although any amount of coins above 1,999,999,999 is displayed as 1,999,999,999, it is still handled normally. Maximum limit is not known, but most likely 2,147,483,647, the 32-bit maximum.
Before 2.0.0, the icon used to be a golden coin with the cent symbol on it,() but it is now a golden coin with a My Singing Monsters font "M" on it. ().
Those little green gemstones are the "premium" resource of the game, and have many uses, which include:
The Market can be used to obtain Diamonds in two ways:
1) Purchasing with real money (watch for sales).
2) For free. Free Diamonds require downloads of third-party apps, and come only in small quantities. This option is not available to PC players.
Before Version 2.0.0, it appeared less shiny and colored more like an emerald (), but now appears more light-blue and appearing more lustrous. ().
The sole use of Treats, sometimes called food, is to level-up Monsters. The specific amount required depends on the complexity of the monster. More information can be found on the Feeding page.
When a monster is leveled up, many beneficial things happen. This makes treats valuable and almost mandatory to progress in the game. Leveling up increases the income rate, the ability to make monsters breed (level 4) and the ability to be placed in other islands through teleportation (level 15).
As monsters do not get hungry, baking huge quantities of food constantly may not be good when trying to save coins, but will certainly be advisable if the player can use the food to take his monster raising skills to a high level.
More experienced players have established strategies to enable efficient Food Production. All treats cost the same per unit regardless of quantity, but the rate of production per unit varies with the chosen quantity.
Food can also be used to feed your monster at Tribal Island, although it is possible to use Coins or Shards to do the same thing too. However, you will only gain by using food.
Producing food is also an excellent way to gain . Normally you will receive 1 for every 2 spent on food production.
Treats are primarily produced in a Bakery by using coins only, but they may also be given as:
Exclusive to the Ethereal and Wublin Islands, shards have the same uses as coins, but can only be produced by Ethereal Monsters or bought in the Market with coins, diamonds, or real money. Monsters "generate" shards on Ethereal Island in much the same way that they earn coins on other islands: the shard earning rate is proportional to monster level and increases with monster happiness. There is a limit to the number of shards a monster can hold which is proportional to the monster's level, but is not affected by the monster's happiness. When a monster's shard count reaches 75% of the maximum value, a balloon with a shard icon appears over the monster, as a hint to the player to collect the shards. Wublin's will also produce shards 31% of the time.
Starpower is the currency that allows players to buy exclusive items at the StarShop.
Even though it was first introduced in the 1.3.5 update, it only came into practical use after the 1.3.6 update, when the Starshop was first released. Before then, Big Blue Bubble had posted a sneak peak of Starpower's future use.
New icon in version 2.0.0 () replaced ().
You get Starpower from rewards in Tribal Island, mainly by leveling up your tribal monster.
Keys are a currency first released in the Version 1.4.2 update. They are used to purchase Dipsters. Each Dipster costs 1 on Plant Island, 2 on Cold Island, 3 on Air Island, 4 on Water Island and 5 on Earth Island.
New icon in version 2.0.0 () replaced ().
As gifts from friends. One free can be gifted every 7 days to one friend (formerly every 30 days). There is no way to find out who sent it.
Unlike other currencies, the cost of a Relic increases with each exchange: the first costs 3 , the second 6 , the third 9 , the fourth 12 , the fifth 19 , the sixth 27 , the seventh 39 . After that, the exchange rate is 50 diamonds per relic. This resets daily, at a preset time.
Before version 1.3.6. Diamonds could be used to feed Tribal Monsters.
It was probally removed due to accidental feeding.
Wublins can generate random amounts of currency of all types, except Starpower, Relics or Keys.
