Idle Planet Miner Credit Spending & Mothership Rooms Guide

Player question: What should I spend my credits on in Idle Planet Miner, and what do players say about the Lounge room?

I like these games and play them myself. Complete guides are hard to find online, so while playing I collect community experience from Reddit, add a little of my own notes, and put this site together—hoping it helps. Thank you.

Quick answer

Community Knowledge Players give different orders. u/StudyLegitimate2550: Robotics to level 4 first, then unlock the Lounge, then balance levels, prioritizing the level-11 rooms and the Lounge at a 2:1 ratio with Engineering, Forge and Workshop.[4] u/strange143: balance unlocking new rooms and investing in the rooms you have.[1] u/crowdedhoney: get rooms and manager slots into the mid-teens before pumping resources into modules.[1]

What do players say about the Lounge?

Community Knowledge In thread 1wmf5rt[1] a player with 144 credits asks whether to buy new rooms “so I could get the lounge eventually”; u/Fuzzy-Disk8999 reports that the next room they can buy is the Lounge, and u/Rhino1over answers “Robotics 100%”. In thread 1wn79w3[4] the original poster lists the Lounge as “(+Credits)” among rooms they can buy for 133 credits, and u/StudyLegitimate2550 says to unlock the Lounge after Robotics level 4 and keep leveling it as long as its cost isn’t twice as much as Engineering, Forge or Workshop.[4]

One player celebrates reaching a level 60 Lounge (thread 1waoy66)[2]; in the replies, u/Dry-Bicycle-6858 notes there are rooms where one level is more expensive than the Lounge from level 0 to 60.[2]

What do players say about the level-11 rooms?

Community Knowledge u/sebkraj (thread 1wmily8[5]): “The rooms that max out at level 11, max those first.” u/Striker_AC44 in thread 1wm2w60: “What you need is to max out the L11 rooms. One of those halves the crafting cost of items… Another halves the smelting requirements. Once you max those rooms the game gets a whole lot ‘easier’.”[3]

The posts do not name which rooms those are. u/StudyLegitimate2550 lists Robotics as a level-11 room and treats Engineering, Forge and Workshop as separate “main rooms”, advising to level the level-11 rooms instead if the main rooms’ costs become twice as much or more.[4]

What do players say about Robotics?

Community Knowledge The original poster of thread 1wn79w3[4] lists “Robotics lvl 1 - Rover scan time - 10%” among their rooms. u/StudyLegitimate2550 says to rush Robotics to level 4 straight away; u/M1sterM0g says the rover room allows the higher class of searches, which get stars and higher managers; they are not for short galaxies but for the “overnight duty” ones.[4]

When do players say to shift from rooms to modules?

Recommendation In thread 1wmf5rt[1] u/crowdedhoney: “Since you have a blue in each slot then you are good on modules for now. Modules take tons (read: TONS) of credits to build out to their full mid/late game potential.” They advise getting rooms into at least the mid-teens and manager slots into at least the mid-teens (with at least a 4⭐ in each slot) before going back to modules; the next step is to roll up purples for each slot, then purples with an “S”.[1]
