What the Buck skill tree

The What the Buck skill tree is the big money tree you rebuild every shift. It opens for $0 after your first few minutes, its first node adds +$3 to every $1 bill, and from there it branches by denomination, from $1 up to $100. confirmed Every special bill, the flamethrower, diamonds and Investment Papers are unlocked here. confirmed

How the skill tree works

• Mr. Buck calls to tell you the skill tree is open; the first node costs nothing. confirmed
• Nodes cost money, not Prestige Points. A node only becomes buyable after the one before it is complete (“complete previous”). confirmed
• Ending a shift resets the tree, unless you buy the prestige node that keeps every skill tree upgrade (40 PP on release day). confirmed
• Maxing every node in a single shift earns Nothing Left to Buy. confirmed

Over 240 upgrades are spread across the panels, the skill tree and the prestige tree, and the skill tree holds most of them. confirmed

What the Buck skill tree branches

Each money branch carries income nodes for its bill, a chance node for the next bill, prestige-progress nodes and one big unlock: confirmed

Branch	Big unlock	Also in the branch
$1	Electric Bills	+$3 income, +40% income, prestige coins (2% chance)
$2	Golden Bills, gold spreading on touch	$2 chance, $2 income, “ATM no longer withdraws $1 bills” (needs Bill Value 5)
$5	Explosive Bills	$5 income, blast damage and radius
$10	Collector Bills	$10 chance (about $11M on release day), collector capacity and payout
$20	Flamethrower and Fuel Bills	fuel, fire damage, burn spread
$50	Diamonds	diamond value, spawn chance, shards
$100	Paper Trail (Investment Papers)	share value, paper payout

In a Japanese release-day clear, the player had unlocked “up to the $50 one” by the end of the third shift and bought Paper Trail in the next. confirmed

Skill tree guide: the buying order

1. $1 income nodes and prestige coins. Coins fill the prestige bar fastest early on.
2. Electric Bills as soon as they appear; lightning clears bills you never touch.
3. Prestige-progress nodes before you end your first and second shifts, so each shift pays more PP.
4. $2 chance, then Golden Bills and the gold-on-touch node.
5. $5 and Explosive Bills. Chains of explosions clear a crowded table.
6. $10 chance, then Collector Bills. The collector became the top earner in release-day runs. confirmed
7. Remove $1 bills only once $2 and $5 pay more.
8. From there, one branch per shift: flamethrower, diamonds, papers.

When to stop buying and end the shift

The tree gets steep: nodes jump from hundreds of thousands to tens of millions within a branch. confirmed When every affordable node would take minutes of income, end the shift and spend your Prestige Points. The release-day 100% player completed the whole tree within one shift about 91 minutes into his run, after keeping panel upgrades between shifts. confirmed

Skill tree unlock achievements

Seven achievements come from skill-tree unlocks: Electric Bills, Explosive Bills, Golden Bills, Collector Bills, Flamethrower, Diamonds and Paper Trail. confirmed The eighth, Nothing Left to Buy, needs the whole tree in one shift.

Common skill tree mistakes

• Spending everything on income and nothing on prestige progress before ending a shift.
• Removing small bills before the next branch pays more.
• Forgetting that a node needs the previous one complete; look for the “complete previous” note.
