You just hit Level 12. The game plays a little fanfare. Two new islands light up on your map: Wublin Island and Ethereal Island. Each costs 500,000 coins. You have been saving for eight days. Your Plant Island has six monsters and a level-3 Castle. Your Cold Island has three monsters. Air Island is basically empty because you bought it yesterday and ran out of coins. You look at your coin bank: 520,000. You buy Wublin Island. Then you see Ethereal Island still glowing on the map and you panic — what if you miss out? You scramble, sell your only big decoration, collect from every island, and hit 500,000 again. You buy Ethereal Island too. Now you have 12,000 coins, three barely-populated Natural islands, two completely empty premium islands, and a level-3 Castle that cannot hold enough monsters to breed the eggs you need. You open Wublin Island. It is a graveyard of stone statues that demand eggs you cannot make. You open Ethereal Island. It is empty and requires Ethereal monsters with a 1% breed chance that you have never seen. Your coin income dropped to nothing because you sold your decoration. You are now stuck for two weeks. This is the Level 12 trap, and it catches four out of five players.
The tutorial in My Singing Monsters teaches you to place monsters and collect coins, but it never teaches you the one rule that determines whether your account thrives or stalls: the order in which you unlock islands matters more than which monsters you breed. A player who unlocks islands in the right order reaches level 30 in three weeks. A player who unlocks them in the wrong order reaches level 30 in three months. Both players play the same amount of time. Both players have the same luck. The only difference is timing.
Why Players Unlock Islands in the Wrong Order
Most players do not fail because they are bad at the game. They fail because the game presents unlocks as rewards instead of investments. Here are the five specific mistakes that destroy progression.
Treating level unlocks as green lights. When Wublin Island lights up at Level 12, the game frames it as an achievement. It is not. It is a 500,000-coin infrastructure project that requires three fully functional Natural Islands to support it. The level requirement is a minimum bar, not a recommendation. Players see the unlock, assume they are meant to use it immediately, and spend their entire coin bank on an island they cannot feed.
Buying new islands before filling old ones. A Plant Island with ten monsters produces roughly 20,000 coins per hour. A Cold Island with two monsters produces 800. If you buy Cold Island when Plant Island is half-empty, your total income actually drops because you spent 50,000 coins that could have gone toward breeding more Plant Island monsters. The correct move is to fill Plant Island to 70% capacity first, then buy Cold Island with the surplus income. Most players do the opposite.
Spreading resources across too many islands at once. Every island you own demands Castle upgrades, breeding structures, and monster food. A player with five islands and level-3 Castles on each is weaker than a player with three islands and level-6 Castles. Castle levels determine bed capacity, which determines monster count, which determines coin production. Five weak islands generate less than three strong ones.
Ignoring Castle upgrades in favor of novelty. A Castle upgrade costs 50 to 200 diamonds and increases monster capacity permanently. A new island costs coins and generates nothing until it is populated. Players will spend 500,000 coins on Earth Island before spending 50 diamonds on a Plant Island Castle upgrade. The Castle upgrade is a permanent 30% income increase. The empty Earth Island is a 500,000-coin liability.
Buying diamond-cost islands before the coin economy is stable. Mirror Islands cost diamonds, not coins. Players see them as a shortcut to more income and buy Mirror Plant Island for 100 diamonds before their main Plant Island is full. Then they have two Plant Islands, both half-empty, and no diamonds left for Castle upgrades. Mirror Islands are multipliers, not foundations. They multiply zero income into zero income.
The Optimal Island Unlock Order by Level
The progression path that maximizes coin income and minimizes downtime follows a simple rule: fill before you expand, and upgrade infrastructure before you buy novelty. Here is the exact order.
Level 1-4: Plant Island Only
Do not buy Cold Island yet. Plant Island is free, has the fastest breed times, and the lowest feeding costs. Your only goal is to reach 8-10 monsters and breed your first Entbrat using Bowgart plus Noggin. An Entbrat is a 4-element monster that produces roughly 200 coins per minute at level 10. Two Entbrats fund your entire early game. Do not look at other islands until Plant Island is at least 70% full and you have one Entbrat singing.
Level 4-7: Cold Island (50,000 Coins)
Once Plant Island generates 15,000 coins per hour consistently, buy Cold Island. You should have the 50,000 coins saved in under four hours. Immediately breed four to five Cold Island monsters using eggs from your established Plant Island stock. Fill Cold Island to 60% before moving on. Do not buy Air Island the moment you hit Level 9. Wait until Cold Island is producing at least 8,000 coins per hour.
Level 7-10: Air Island (100,000 Coins) and Water Island (250,000 Coins)
Air Island unlocks at level 9 for 100,000 coins. Water Island unlocks at level 10 for 250,000. Buy Air first, populate it to 60%, then save for Water. By this point you should have level-4 or level-5 Castles on Plant and Cold. If your Castles are still level 3, stop buying islands and upgrade them. A level-5 Castle holds 40 monsters. A level-3 Castle holds 20. That difference is 20 monsters worth of coin production.
Level 10-13: Earth Island (500,000 Coins) and Castle Upgrades
Earth Island is the final Natural island and costs 500,000 coins. Do not buy it until all four previous Natural islands are at least 60% full. Once Earth Island is purchased, your focus shifts entirely to infrastructure. Upgrade every Natural Island Castle to at least level 5. Buy second breeding structures on Plant, Cold, and Air. Your goal is not to unlock more islands. Your goal is to make your five Natural islands so efficient that they generate 100,000 coins per hour combined.
Level 13-15: Gold Island (500,000 Coins) and Tribal Island (150,000 Coins)
At level 15, Gold Island and Tribal Island become available. Gold Island lets you teleport level-15+ duplicate Natural monsters to produce Gold. Tribal Island gives you weekly diamonds for contributing to a tribe. Both are passive income sources that do not strain your breeding infrastructure. Buy Gold Island first, then Tribal Island. Do not unlock Wublin Island yet even though it has been available since level 12.
Level 15+: Wublin Island (500,000 Coins)
Only now, with five full Natural islands and level-5-plus Castles, should you buy Wublin Island. You need the ability to breed replacement eggs continuously across three or more islands without emptying your nurseries. Start with Zynth statues only. Five Zynths give you a stable base of passive coins, treats, shards, and occasional diamonds every 12 hours. Do not diversify into other Wublins until your Stoney Bridge is at level 4.
Level 20+: Fire Haven (100,000 Coins)
Fire Haven introduces the Fire element and uses Shards instead of coins. It is cheap to unlock but expensive to populate because Fire hybrids require specific breeding combinations and longer breed times. Only buy Fire Haven after your Wublin Island has at least five active Zynths generating resources.
Level 25+: Magical Sanctum (250,000 Coins) and Fire Oasis (250,000 Coins)
Magical Sanctum and Fire Oasis are endgame islands. Magical Sanctum introduces Magical monsters that produce Stardust. Fire Oasis completes the Fire-element collection. Neither generates coins, so they do not accelerate your core economy. Buy them when you have at least 2 million coins in reserve and nothing else to spend them on.
Mirror Islands: After Natural Islands Are Maxed
Mirror Islands duplicate an existing Natural island and cost diamonds. Mirror Plant Island is the most valuable because Plant Island has the highest early-game coin density. Buy your first Mirror Island only after all five Natural islands have level-7 Castles and full monster populations. They are luxury multipliers, not necessities.
| Phase | Level Range | Island | Cost | Priority Condition |
|---|---|---|---|---|
| Early | 1-4 | Plant Island | Free | Fill to 70% before next |
| Early | 4-7 | Cold Island | 50,000 coins | Plant Island at 70% |
| Mid | 7-10 | Air Island | 100,000 coins | Cold Island at 60% |
| Mid | 10-12 | Water Island | 250,000 coins | Air Island at 60% |
| Mid | 12-13 | Earth Island | 500,000 coins | All prior at 60%, Castle L5+ |
| Late | 15 | Gold Island | 500,000 coins | All Natural islands full |
| Late | 15 | Tribal Island | 150,000 coins | After Gold Island |
| Late | 15+ | Wublin Island | 500,000 coins | 3+ islands can sustain breeding |
| Endgame | 20+ | Fire Haven | 100,000 coins | 5+ Wublins active |
| Endgame | 25+ | Magical Sanctum | 250,000 coins | 2M+ coin reserve |
| Endgame | 27+ | Fire Oasis | 250,000 coins | After Fire Haven is full |
| Luxury | Variable | Mirror Islands | Diamonds | All Natural islands maxed |
The Advice That Sounds Wrong But Is Right
Most MSM guides repeat the same safe advice: save diamonds, breed efficiently, be patient. Here are three recommendations that will feel incorrect the first time you read them.
Do not unlock Wublin Island at Level 12. Wait until Level 15 or higher. The game tells you it is available. Your instincts tell you to buy it immediately because it is new content. Resist. Wublin Island is not a reward for hitting level 12. It is a 500,000-coin breeding factory that requires level-4 monsters on at least three Natural Islands and enough nursery capacity to replace every egg you zap. At level 12, you do not have that. You have a level-3 Castle and a single nursery slot. Unlocking Wublin Island early turns your account into a coinless statue garden for two weeks.
The most boring island is the most important. Plant Island is repetitive. You see it every day. It has no special mechanics, no exclusive currency, and no flashy monsters. That is exactly why it is your entire economy. A fully optimized Plant Island with level-15 monsters, max happiness, and a level-7 Castle produces more coins per hour than an empty Ethereal Island, an empty Wublin Island, and an empty Gold Island combined. Never neglect Plant Island because it is boring. Boring is reliable. Reliable is what buys everything else.
Delay Gold Island longer than you want to. Gold Island unlocks at level 15 and feels like the next logical step. But if you teleport your best Plant Island monsters to Gold Island before you have duplicates, you gut your coin production. Gold Island requires level-15 monsters, which require massive food investment. If you rush to level 15 a monster just to teleport it, you will spend 50,000 treats and lose your best coin producer on Plant Island. Only teleport duplicates. If you do not have a duplicate, Gold Island can wait.
Mirror Islands are worth the diamonds before you think they are, but only if you think they are expensive. A Mirror Plant Island costs diamonds and gives you a second Plant Island bed layout. Most players avoid it because it costs premium currency. But a Mirror Plant Island with the same monster layout as your main Plant Island effectively doubles your diamond mine output and your coin collection from the island’s specific monsters. The catch: it only doubles what you already have. If your main Plant Island is weak, the Mirror Island is weak. Buy it after your main Plant Island is maxed, not before.

My Singing Monsters is an infrastructure game wearing a music game costume. The players who advance fastest are not the ones who breed the rarest monsters first. They are the ones who fill Plant Island before buying Cold Island, who upgrade Castles before buying Earth Island, and who treat every new island unlock as a liability until they have the income to fund it. Wublin Island will still be there at level 15. Ethereal Island will still be there at level 20. The coins you save by waiting compound into faster progression across your entire account. Patience is not just a virtue in MSM. It is the only currency that never depreciates.
