All seven Tap Simulator Reborn islands in order, the portal prices players report, the double jump Gem costs and what each island unlocks.
Tap Simulator Reborn Islands and Portal Costs
Tap Simulator Reborn runs on seven islands, from the spawn bridge to the Shadow Realm, and each one exists to raise the Coin scale by two or three orders of magnitude. Getting between them is the main long-term decision in the game, because every island can be entered two ways: pay the portal fee in Coins, or buy a double jump with Gems and parkour up.
- Islands — seven, in a fixed order from spawn to Shadow Realm
- Two entry routes — Coin portal fees, or Gem-funded double jumps
- Reported price range — roughly 7 million Coins at the first portal to 19 quadrillion at the last
- What each island brings — a new egg pool, plus its own machinery or minigame
- Confidence warning — portal figures come from community trackers and sources disagree
The Island Ladder
The order below is the one every source describes, and the island names are corroborated by recorded playthroughs that name them directly. The costs are community reported figures, and the section after this table explains why you should treat them as a shape rather than a shopping list.
| # | Island | Reported portal cost | Alternative route | What is there |
|---|---|---|---|---|
| 1 | Spawn Island | Starting area | 700 Tap Power lowers the bridge | Basic eggs, early rebirths, the golden crafting machine, the Gem tree |
| 2 | Sky Island | 7 to 10 million Coins | First double jump, reported at 700 Gems | Sky eggs, a tap chest |
| 3 | Autumn Island | 13 billion Coins | Second double jump tier | Shrine blessings, a dig site, pumpkin eggs, a giant pumpkin target |
| 4 | Mushroom Island | 500 billion Coins | Third double jump tier, reported around 440,000 Gems | A pet defence minigame, mushroom and spore eggs |
| 5 | Desert Island | 45 trillion Coins | Fourth double jump tier, reported around 1.2 million Gems | A pyramid tap chest, prickly cactus targets, the cactus egg |
| 6 | Crystal Cave | 590 trillion Coins | Parkour route using Gem jump upgrades, reported around 3 million Gems | The diamond crafting machine, a crystal mines minigame, crystal and geode eggs |
| 7 | Shadow Realm | 19 quadrillion Coins | Final jump tier | The rainbow crafting machine, the enchanting station, the void egg |
Two things stand out immediately. The first is that the portal prices multiply by roughly a thousand each step, which is a deliberate design choice: it means each island's Coin income has to be an order of magnitude above the last, and pets are what deliver that. The second is that the alternative route is almost always cheaper in real terms, which is why the Gems guide treats double jumps as a legitimate budget line rather than a luxury.
Spawn Island and the 700 Tap Power Bridge
The spawn area is the only island that is not gated by a purchase. Community sources describe it as where the basic egg sits, where the golden crafting machine lives, and where the Gem skill tree panel becomes available.
The one gate is the bridge. Community reports put it at 700 Tap Power rather than a Coin cost, which makes it a soft progression check: you cannot pay to skip it, you have to have tapped and hatched enough for your tap power to reach the threshold. The practical advice is to check the bridge before spending anything on travel, because a new player who buys a double jump before the bridge opens has spent Gems on an island they cannot properly use yet.
Spawn is also where three of the fifteen Shiny Stars are hidden, including one behind the fountain and one behind an egg. Those are free progression, and the Shiny Stars guide has the positions.
Sky Island and the First Real Portal
Sky Island is the game's first genuine decision point. The reported portal fee is in the single-digit millions of Coins, which sounds enormous at spawn and stops sounding enormous within an hour, and the alternative is a first double jump reported at 700 Gems.
The island itself is deliberately thin on systems. It has its own egg pool, which is the point: sky eggs produce pets whose multipliers are calibrated to the millions-of-Coins scale, and arriving with spawn pets makes the island feel like a wall rather than a step up. Recorded playthroughs of the sky island show rainbow-variant pets, which is the visual cue that you have moved up a tier.
The tap chest on this island is one of several across the game. Destructoid's description of Reborn mentions breaking chests as part of the core Coin loop, and the islands each carry their own chest variants.
Autumn Island: Shrines, Dig Sites and the Pumpkin
Autumn is the first island with side systems rather than just a better egg stand.
Community sources describe two features that do not exist earlier. The first is a shrine that grants a temporary blessing, upgrading to a second tier after about ten minutes and a third after around twenty-five, with the higher tiers improving luck and golden rates. If that is accurate, the shrine is a free buff that rewards sitting on the island rather than island-hopping, and it is the reason high-volume hatchers spend extended sessions here.
The second is a dig site that produces pet treats, along with a giant pumpkin target that is one of the map's breakable objects. Recorded playthroughs show players tapping roaming targets around the maps for crafting materials, and the pumpkin is the autumn example.
Mushroom, Desert and Crystal Cave
These three islands are where the game stops explaining itself and simply scales up. Each one follows the same template: a new egg pool, a new target to break, and one distinctive machine or minigame.
Mushroom island has a pet defence minigame and two egg lines, described as mushroom and spore eggs. Desert island has a pyramid chest that behaves like an amplifier of the tap chest mechanic, a cactus target that recorded playthroughs describe as running away from the player until caught, and the cactus egg. Crystal Cave is the outlier: community sources report that its portal is not the practical route at all, and that players parkour up using accumulated Gem jump upgrades instead.
Crystal Cave matters for one reason above the others. It houses the diamond crafting machine, which is the second rung of the pet variation ladder. Without reaching it, your pets are stuck at golden. The crafting guide covers what that machine does and what it costs.
The Shadow Realm
The final island sits behind a reported 19 quadrillion Coin portal, the largest number in the game's progression, and it is the only place where three separate endgame systems live.
The rainbow pet machine is there, which is the top of the variation ladder. So is the enchanting station, which community playthroughs show consuming Diamonds rather than Coins or Gems. And so is the void egg, the pool that community sources credit with Cerberus, the strongest confirmed non-secret pet in the game at a base multiplier of 192,000.
Recorded playthroughs of the Shadow Realm describe it as visually the largest area in the game, with the new egg, the golden machine and the enchanting station all visible on arrival. If you are planning a session around a secret pet hunt, this is where the pools with the most valuable pets sit.
Two community wikis track Reborn's island costs and they diverge sharply on the later islands, sometimes by two or three orders of magnitude. The order of the islands is reliable because recorded playthroughs name them directly. The exact portal figures are not. Treat the table above as a description of the ladder's shape, and read the price off the in-game panel before you save toward anything.
How to Decide Between Paying and Jumping
The rule is arithmetic. Compare the portal fee to what the same Gems would buy you elsewhere, and remember that Gems come only from rebirths.
At sky island the Coin portal is a few million Coins, which a mid-game pet team earns quickly, so paying with Coins and saving the 700 Gems for the Auto Clicker and tap power is usually right. By mushroom and desert, the portal fees have moved into the hundreds of billions and trillions while the jump prices are reported in the hundreds of thousands of Gems, and the exchange rate tips decisively toward jumping.
The practical test: if the portal fee is more than a session's Coins, jump. If it is less, pay it and keep the Gems.
Official source: Tap Simulator Reborn on Roblox — the description lists "Unlock new islands" as one of the game's four headline systems, and the official group page confirms the developer behind both this experience and the original Tap Simulator. Island names are corroborated by community location walkthroughs that travel through them in order.
FAQ
How many islands are in Tap Simulator Reborn?
