Spending Goals
Spending for this offer is mostly reimbursed with the exception of the “Remove All Ads” option for $17.99, with reward points only valued at $10.67.
Both the ad removal and premium pass purchases must be completed within the first 10 days of play. Generally, these types of purchases should be completed on the first day of play to get the maximum benefit.
Total spending for this offer is $40 with $32 in reimbursement. The point earnings from Planet 3 through Planet 25 is 1,584 or $10.56, this is enough to cover the shortfall in spending goal reimbursements.
Essentially, if you decide to complete all spending goals, you will be at breakeven by the time you reach Planet 25.
Gameplay
As with most idle tycoon games, this involves a lot of micromanagement and careful decisions on where to spend resources to gain the maximum benefits.
Speed in clearing Planets is important to reach out goals within the 30 day time limit on the offer. The sole Bonus point reward comes by reaching Planet 30 within 7 days of play.
Tips
Set your upgrade buying to “Next”, since that indicates when you’ll get a large increase.
Make sure you’re claiming your sporadic earnings (minigames, free powerup, etc), they’re easy to miss.
If you’re going to be offline for a while, stock up on power to avoid hitting an ice level whilst offline.
Prioritise quests, since the rewards are usually pretty good.
Use up TNTs and similar level-clearing powerups as soon as possible, to progress to more valuable ores.
Limited time offers: Complete Season 15 (4 days) $6.00 and Complete Season 30 (7 days) $18.00.
Episode 15 can be cleared within the 4 day limit if you purchase the Monster Pass. However, Episode 30 cannot be cleared in just 7 days without more spending.
All shops may be temporarily increased by watching an ad to activate a boost. This can be done 3 times for a 12 hour boost.
You can watch an ad to double your accrued offline idle income.
Tapping on the bird flying across the screen can earn Cash, and occasionally you can watch an ad for double rewards.
Trading cards counts towards “Get Cards” task.
To get Building Cards you need to achieve Customer Bonuses. This occurs when you reach a customer milestone by filling up the purple/pink bar on shop.
Customer Cards are available by Trading, purchase in the Shop using NanoSpider coins, or from Coffins and stage advances.
Surveys through Revenue Universe can be completed to earn extra Dream Crystals.

Monster Pass
The pass includes special characters that boost the high tier shops. Lots of NanoSpiders, Skip Tickets, and some Dream Crystals.
Items must be claimed individually. This is helpful if you want to save some rewards for later, such as the ad skip tickets.
The game maps are called Episodes and proceed in stages of business development. Each level includes several objectives that must be completed before the player can advance to the next Episode.
Warning: Completed goals DO NOT carry over to the next episode. Make sure to collect all completed goals before advancing.
Shops will generate cash which can be tapped on to collect income after the timer bar has filled. Upgrading shops will boost the amount of cash they generate. Assigning a Monster to a shop will enable automation and passive cash generation.
Monsters (managers) assigned to select shops will improve the income generation speed/amount. Monsters must be upgraded to continue using automation as the game progresses.
Focusing your upgrades on the higher tier shops will provide a much greater return on investment in the end game. Especially enabling automation for the periods when you go to bed.
As you advance through the Episodes, the amount of cash generated by low tier shops will become inconsequential. However, missions will likely require ineffective upgrades to progress the storyline.
Events
Throughout gameplay Event maps will become available and will run concurrently with the main map. Additional resources can be acquired on the Event maps.
However, be mindful of spending premium currency trying to clear the Events or rank high on the leaderboard. This can detract from the efforts spent clearing the goals on the main map.
Even small rewards from the Event maps can be useful in clearing the primary objectives. You can also expect regular players to spend cash to rank high on the leaderboards.
Event Strategy and Tips
These event maps use a simplified format for upgrading shops.
There are several versions of the Event maps and some use different rules. Some versions will use a single Card for Cash or Time upgrades that will allow automation, while each individual shop will still have the regular managers.
This means you only need to focus on upgrading a single Card if you just want the passive returns.
In other versions there are separate cards for all functions. And in others still a very simple 1-2 day timeframe with limited rewards.
In all events, the following benefits should apply.
At Event completion, we receive 25% of our leftover event currency as NanoSpider coins, up to a max of 500 coins. This means we want to end the event map with 2,000 event currency.
Completing tasks on the Event map will contribute to the Monster Pass tasks.
There are 59 cards in total (as of Feb 2026). Cards come in rarity ranks of Common, Rare, Epic, Legendary, and Event.
Some cards will increase the cashflow of a shop while others improve the speed cycle.
The cost to purchase cards in the shop depends on their rarity, with Common costing just 5 coins to start. The cost to purchase a card increases by 1 coin for each one you buy until either the shop refreshes or you reach a new Episode.
Rare cards have a base cost of 15 Coins. Epic cards start at 50 Coins each. Some special cards are only available from the Monster Pass.
Episode Clear Multiplier
A unique card, the spider “Lady” will boost the multiplier by a fraction when clearing episodes. I strongly suggest NOT spending any coins on the spider. A better option would be the Epic card Janice, who doubles the multiplier.
Statue Cards
Statue cards are earned from the Events and will place idle reward statues on your map area below the shops. The Owl and Eyeball statues will provide Coins every day. The Eyeball has a faster cycle period.
Ranking high in Events is the only way to get cards to upgrade the statues. Expect Whales (big spenders) to take the top spots in all events. So mostly these statues will remain level 1 during the offer period.
