Choose Upgrades for the Problem in Front of You
The best upgrades are the ones that turn a struggling run into enough income to cover the next bill. In Bills Must Be Paid, a powerful-looking node can still be a bad purchase if it does not fix what is limiting your current run.
Watch the desk instead of following a rigid skill tree route. Your hammer, stamina, available Piggies, and income all need to work together. If one part falls behind, buying more of something else usually wastes cash that could have protected your next payment.
| What you see during a run | Your current bottleneck | Best upgrade focus |
|---|---|---|
| The desk is empty with stamina remaining | Not enough targets | Starting Piggies, spawn effects, spawn rate |
| Piggies survive many hits | Damage is too low | Base Damage, critical stats, better hammer |
| The run ends with killable Piggies left | Stamina is too low | Maximum stamina, stamina efficiency |
| You clear the desk but bills outpace earnings | Income value is too low | Loot, Luck, glowing rewards, value effects |
| One tough Piggy absorbs most of the run | You need a kill breakpoint | Hammer upgrade, damage, crit damage |
Use ordinary runs to diagnose the issue. A rare jackpot can make an underpowered setup look better than it is, so wait for the same problem to appear more than once before committing most of your reserve.

Best Early Upgrade Order
A safe early path prioritizes reliable kills first, then enough targets and stamina to use those kills. Damage is normally the most useful opening investment because it reduces the number of swings needed to break basic Piggies.
Once opening targets die comfortably, add only the support upgrades your desk actually needs. The goal is a stable loop: targets are present, they die at a reasonable pace, stamina lasts long enough to use the available opportunities, and earnings leave the next bill secure.
A practical early order is:
- Buy Base Damage until opening Piggies no longer consume most of the run.
- Take a modest stamina upgrade if your run ends with targets still available.
- Add Starting Piggies or spawn effects only when you are waiting for new targets.
- Choose radius or collateral effects when multiple Piggies regularly share the desk.
- Add Attack Speed after kills are already reliable and targets remain available.
- Shift toward Loot and Luck once combat no longer blocks progress.
| Upgrade type | Buy it early when... | Delay it when... |
|---|---|---|
| Base Damage | Current Piggies need too many hits | You already one-shot targets and lack spawns |
| Stamina | Killable Piggies remain when the run ends | A durable Piggy cannot be killed anyway |
| Starting Piggies | The opening desk is sparse | The desk already stays crowded |
| Spawn Rate | You repeatedly wait for targets | Existing Piggies survive too long |
| Hit Radius / collateral | Several targets can be hit together | Targets are too spread out or too durable |
| Attack Speed | Targets die quickly and stamina supports more swings | You are swinging at an empty desk |
Do not treat every unlocked node as a purchase recommendation. Early cash is especially valuable because it may be the difference between paying a bill on time and entering a weaker recovery cycle.
Damage, Speed, and Hammer Priorities
Attack Speed feels immediately satisfying, but it is not automatically one of the best upgrades. Faster weak swings still spend stamina, and they do little when the desk is empty or a high-health Piggy will not die before the run ends.
Prioritize damage when a new Piggy tier creates an effective health wall. Base Damage, critical chance, critical damage, first-hit effects, and a stronger hammer can reduce the number of required swings. That creates more value per stamina point and often improves the entire run at once.
Attack Speed becomes excellent after your build reaches a stable damage threshold. More swings then mean more completed kills, more chances to trigger on-hit effects, and faster use of area or collateral damage.
| Situation | Better choice | Why |
|---|---|---|
| Crowded desk, durable Piggies | Damage or critical upgrades | More targets do not help until they can be removed |
| Crowded desk, quick kills | Attack Speed, radius, collateral | Extra swings convert directly into more clears |
| Empty desk, stamina left | Starting Piggies or spawn upgrades | There is nothing useful for speed to hit |
| One valuable Piggy blocks the run | Hammer or direct damage | A reliable breakpoint matters more than volume |
| Several nearby weak Piggies | Radius or multi-target effects | One swing can complete multiple kills |
Hammers are packages of trade-offs rather than automatic upgrades. Compare their damage, critical chance, radius, and speed against your current bottleneck. A faster, wider hammer may excel at clearing weak crowds, while a stronger or critical-focused hammer can be better for durable targets.
Buy a new hammer when it produces a meaningful kill breakpoint and still leaves enough money for the next bill. If your current hammer already clears efficiently, save the money for a more urgent upgrade or future bill.

Scale Income Without Risking the Bill
Loot, Luck, glowing-reward effects, and similar income multipliers are strongest after the build can consistently destroy Piggies. They improve the value of successful kills, but they do not solve a desk full of targets that survive every hit.
Separate bill money from upgrade money before every major purchase. If you have $500 and an upcoming bill costs $350, your real upgrade budget is $150. Spending the entire amount on a promising hammer can still be a loss if it makes the bill unsafe.
| Upgrade category | Best time to invest | Main benefit | Main risk |
|---|---|---|---|
| Loot | You already clear available targets | More value from each destroyed Piggy | Does not solve low damage |
| Luck | Income is stable over several runs | Better access to favorable random rewards | Results can be inconsistent |
| Glowing or high-value rewards | You can kill enough targets to trigger them often | Strong long-term income scaling | Weak if runs end early |
| Midas-style multipliers | Late-game, stable build | Expands earnings from successful runs | Poor emergency purchase |
| Super Jackpot | Deep into a comfortable economy | Long-term farming potential | High cost can endanger the bill reserve |
Avoid buying expensive late-game effects just because they are available. Super Jackpot and other large investments are better treated as farming tools, not emergency progression fixes. Purchase them only after regular income comfortably covers bills and core combat upgrades.
Bankruptcy is also part of progression, not simply failure. When a run cannot reasonably meet future bills, a reset can convert progress into permanent power. Rings and bracelets purchased with prestige currency improve later cycles, making the next start faster and more reliable.
FAQ
What are the Bills Must Be Paid best upgrades for a new player?
Start with enough Base Damage to break early Piggies efficiently. Add stamina if killable targets remain when a run ends, then add Starting Piggies or spawn upgrades if the desk becomes empty. Attack Speed is usually better after targets die quickly and remain available.
Should I buy Attack Speed early?
Not by default. Attack Speed is weak when you are waiting for Piggies or when your hits are too weak to finish them. Buy damage first against tough Piggies, and buy target-generation upgrades if the desk is empty.
When should I upgrade my hammer?
Replace your hammer when a new option solves a clear issue, such as a damage breakpoint against a durable Piggy or better area coverage for crowded desks. Do not buy it if the cost puts the next bill at risk.
Are Loot and Luck upgrades worth it?
Yes, but mainly after combat is stable. Loot and Luck improve income from completed kills; they are not a substitute for damage, stamina, or enough targets.
How do I know whether I need stamina or more spawns?
Check how a normal run ends. If stamina remains but the desk is empty, buy more starting targets or spawn effects. If Piggies remain and are already killable, improve stamina. If one Piggy survives almost the entire run, prioritize damage instead.
