When you finally hit your first Reboot, the most critical decision you make is how to spend your hard-earned R.A.M. (Retired Adult Memories). The best permanent upgrades order Slots & Diapers prioritizes meta-currency acceleration first, followed by Gambler automation, and finally Liquid Asset scaling. For your initial resets, always dump your R.A.M. into Mega Jackpot Chance to guarantee faster subsequent Reboots, then immediately pick up Auto-Rollers to keep your veteran seniors spinning while you idle.
In Parodie Games' absurd casino simulator, progression isn't just about watching a number go up—it's about mathematically optimizing a chaotic floor of elderly gamblers. If you waste your meta-currency on cosmetic diaper upgrades or manual click multipliers too early, you will brick your run and grind your chip generation to a halt. This guide breaks down the mathematically optimal path through the Perma-Skill Tree to reach the elusive "The 1%" achievement and build an infinite engine of accumulation.
The Math Behind the Madness: The Double-Dopamine Economy
Before mapping out the exact skill tree path, you have to understand the bottleneck in the game's three-tier economy. Slots & Diapers operates on a "Double-Dopamine" loop that juggles three distinct resources: Chips, Liquid Assets, and R.A.M.
Chips are your base currency, generated by the machines. You use them to buy the physical hardware—from the basic CraptoMachine up to the high-velocity Digital Machine. Liquid Assets (affectionately tracked as "Craptocurrency" in your stats) are the byproduct of your veteran seniors having "accidents" on the floor. You weaponize these mishaps to trigger powerful, limited-time active skills.
But neither of those resources matter when you hit a progression wall. The only currency that survives a System Reboot is R.A.M. (Retired Adult Memories), which is exclusively extracted by hitting a Mega Jackpot. Because R.A.M. is the sole currency used on the Perma-Skill Tree, your entire casino operation must be built to maximize the frequency of Mega Jackpots. Every decision you make on the floor should be in service of pulling that lever faster and more often.

Early Game: The Best Permanent Upgrades Order Slots & Diapers
During your first few runs (Reboots 1-5), your chip generation is slow, and your veteran gamblers are unoptimized. The goal here is strict utility. You want to escape the manual clicking phase as quickly as possible.
1. Mega Jackpot Chance (Max this first) As of Patch 1.0.2, you can view your exact Mega Jackpot probability in the stats tab. Your very first R.A.M. investments must go into increasing this base percentage. Because R.A.M. is your prestige currency, boosting the rate at which you acquire it creates a compounding snowball effect. A 2% increase in Mega Jackpot Chance cuts the time required for your next Reboot in half.
2. Auto-Rollers (Gambler Automation) Why spin yourself when you can hire the pros? The "Auto-Rollers" node upgrades the base efficiency of your recruited seniors. This ensures that while you are managing the floor layout, the reels keep turning. Upgrading Auto-Rollers early guarantees a steady stream of passive Chips and passive Liquid Assets, completely removing the need to manually crank the machines.
3. CraptoMachine Base Multiplier The CraptoMachine is the first piece of hardware you buy in every single run. By boosting its permanent multiplier, you bypass the agonizing early-game crawl and instantly jump to the Cherry Machine and Bell Machine tiers within minutes of a fresh Reboot.
4. Liquid Asset Capacity Your veteran seniors will generate "mishaps" continuously, but if your storage is capped, those assets go to waste. Upgrading your capacity ensures you can bank enough Craptocurrency to chain multiple active skills together when you finally push for a late-game Mega Jackpot.

Mid-Game Scaling: Weaponizing Craptocurrency
Once you have automated your early game and secured a reliable R.A.M. income, Reboots 6-15 shift focus toward active skill synergies and mid-tier hardware optimization. This is where the game's economy opens up, and your Perma-Skill Tree decisions dictate whether a run takes two hours or twenty minutes.
5. Active Skill Duration Liquid Assets are traded for boosters that temporarily supercharge your casino's output. Extending the duration of these boosters is mathematically superior to increasing their peak multiplier. A longer frenzy window gives your automated seniors more time to trigger a 15X Match, drastically increasing your odds of extracting R.A.M. during a buff window.
6. Bell and Diamond Machine Synergies The mid-game is entirely carried by the Bell Machine and the Diamond Machine. Investing in their specific synergy nodes on the Perma-Skill Tree allows them to feed off each other's multipliers. When placed adjacent to one another on the casino floor, a fully upgraded Diamond Machine will carry your chip production until you can afford the endgame hardware.
7. The Pointer (Cursor Upgrades) While manual clicking is inefficient in the early game, "The Pointer" upgrades become highly relevant in the mid-game when combined with active skills. Upgrading your cursor allows you to spot-click high-value targets during a frenzy, acting as a manual override to push your chip count over the threshold needed for the next machine tier.
Late Game: The Best Permanent Upgrades Order Slots & Diapers
Reaching the endgame (Reboots 16+) means you are hunting for the "Crapto Millionaire" and "The 1%" achievements. The numbers on your screen are now completely unreadable without the Patch 1.0.2 formatting updates, and your floor is a biohazard nightmare of automated efficiency.
8. Dragon Tech (Dragon Machine Multipliers) The Dragon Machine is the bridge between the mid-game and the final tier. It is prohibitively expensive, but investing R.A.M. into the Dragon Tech node reduces its base cost and increases its payout variance. You need a fully optimized Dragon Machine to generate the trillions of chips required to unlock the final tier.
9. Digital Machine Base Yield The Digital Machine is the apex of Parodie Games' hardware hierarchy. It outputs the highest base chip multipliers in the game. Any R.A.M. spent on the Digital Machine yields exponential returns. Maxing out this node is the key to filling every available slot on the casino floor and achieving true infinite scaling.
10. Biohazard Level 1 Storage Expansion To sustain the Digital Machine's massive upgrade costs, you must weaponize an absurd amount of Liquid Assets. The final storage expansions allow you to hold thousands of Craptocurrency units at once. This enables you to trigger "Endgame Frenzy" states that last for several minutes, flooding the floor with enough capital to buy out the remaining skill tree nodes.

Common Mistakes in the Best Permanent Upgrades Order Slots & Diapers
Even with a tier list, players frequently sabotage their own Reboots by falling into new-player traps. The Perma-Skill Tree is filled with nodes that look appealing but offer zero mathematical advantage to your run.
The Cosmetic Trap The "Brand Spanking New Diapers!" achievement baits players into spending R.A.M. on cosmetic upgrades for the veteran gamblers. While it might look hilarious to see your seniors wearing gold-plated under-layers, these cosmetics do absolutely nothing for your chip multipliers or Mega Jackpot odds. Save cosmetics for when you have already maxed out the functional tree.
The Remodeling Tool Fallacy The "Interior Decorator" node reduces the chip cost of moving machines around the floor. Because you only rearrange your floor a few times per run to optimize adjacency bonuses, spending permanent R.A.M. on this discount is a massive waste. The chip cost of moving a machine becomes mathematically invisible once your Auto-Rollers are fully upgraded.
Manual Wake-Ups There is a node that increases the chip bonus you receive when you manually wake up a sleeping gambler (tied to the "Why?" achievement). If you are playing optimally, your seniors shouldn't be sleeping—they should be automated. Investing in manual wake-ups contradicts the entire purpose of the idle economy. Focus on Auto-Rollers instead.

Frequently Asked Questions (FAQ)
What does a System Reboot actually reset in Slots & Diapers? A System Reboot acts as a hard prestige. It wipes your current Casino floor, destroys all your purchased machines, resets your current Chips, and clears your Liquid Assets. In exchange, you keep all harvested R.A.M. and any Perma-Skill Tree upgrades you have unlocked.
How do I extract R.A.M. more quickly? R.A.M. is exclusively tied to Mega Jackpots. To farm it quickly, prioritize the "Mega Jackpot Chance" permanent upgrade, keep your veteran gamblers fully automated with Auto-Rollers, and maintain a high volume of spins across your cheapest machines (like the CraptoMachine) to maximize the sheer number of jackpot opportunities per minute.
Is it worth waiting for a higher 15X Match before Rebooting? No. In the early game, the moment you have enough R.A.M. to purchase the next tier of Mega Jackpot Chance or Auto-Rollers, you should Reboot. Holding out for a massive run with unoptimized machines is mathematically slower than doing fast, frequent resets to build your permanent multipliers.
Do I need to keep the game open to generate Liquid Assets? Yes and no. While offline progression awards you base Chips, Liquid Assets (Craptocurrency) generate much faster while the game is active and your seniors are visually spinning the machines. If you want to maximize active skill usage, leave the game running in the background.
