Lumber Tycoon 2 Logic Items Guide
The September 2026 Logic expansion turned Link’s Logic from a classic gates shop into a miniature computer-engineering aisle. Segment displays, converters, arithmetic helpers, latches, buffers, counters, new XOR-family gates, and selectors let builders create readable signs, calculators, and automata inside a lumber tycoon. This guide explains what the new parts are for and how to reach them — without drowning you in untested circuit dogma.
Reaching Link’s Logic
Pay Hoover for the ferry (commonly $400), ride to the Tropics dock, and follow the road to Link's Logic. The store historically observes hours; if doors are closed, plan your trip or learn the legitimate entry quirks builders use after hours from the inside.
Bring cash and cargo space. Boxed logic parts are easy to misplace on a chaotic ferry return — haul tips in the vehicles guide. Map notes: map guide. Event framing: events & updates.
Segment Displays and Converters
7-segment and 14-segment displays are the headline toys. September 2026 shelf talk puts each display near $3,500, with matching converters near $1,200. Pair each display with its converter — commonly placed one stud behind — so numeric values render correctly. After a converter is active, a seven-segment unit may default to showing zero, confirming the link works.
Some displays include a small hatch / service area for color cycling, perfect for shopfront branding. Fourteen-segment units support richer alphanumeric shapes than classic seven-segment digits alone.

Binary to BCD, Adder, and ADD3
Binary to BCD bridges binary signal patterns into binary-coded decimal expectations that segment-friendly pipelines prefer. Without it, builders reinvent painful translations by hand.
Adder components handle multi-bit addition patterns for calculators, counters feeding sums, or scoreboard math. ADD3 supports the classic decimal adjustment tricks used when building human-readable arithmetic — especially relevant when chaining toward BCD displays.
Start small: add two inputs, show a result, then scale. Spaghetti wiring at continental scale is how servers cry.
SR Latch, Buffers, and Counters
SR Latch gives set/reset memory — hold a state until told otherwise. Useful for doors, modes, and alarm flags.
BUFFER1 / BUFFER2 / BUFFER4 strengthen or organize signal fanout so large builds do not starve distant inputs.
COUNT4 / COUNT8 / COUNT16 tally pulses for clocks, wood-count displays, or minigame timers. Pair counters with segment displays and you get visible feedback customers can read from the road.

NAND, NOR, XNOR, and Selectors
Older Link's Logic stock already covered fundamentals like AND and NOT. The new wave’s NAND, NOR, and XNOR complete more compact logic expressions and equivalence checks.
Selectors (x4 / x8 / x16) multiplex choices — pick which signal path reaches a display or machine. They are quality-of-life monsters for control panels with many modes.
If you are brand new to logic, build a single AND lamp toy before a full ALU. LT2 still has trees to chop when the circuit frustrates you — balance hobbies via money routes.
Build Ideas That Fit a Lumber Tycoon
- Sawmill throughput counters with seven-segment readouts
- Shop price signs that recolor for sales
- Ferry arrival indicators using latches
- Simple calculators for trade negotiations theater
- Security panels that arm with selector modes
Fund materials with Frost or Lava profits rather than draining your axe budget. Displays are glorious; being unable to afford Dynamite because you bought fourteen converters is less glorious.

Wiring Hygiene Tips
Color-code or spatially separate power, data, and display buses when your plot allows. Leave service alleys behind segment converters so you can recolor or replace units without dismantling the storefront facade. Label latches with signs; future-you will not remember which SR pair arms the gate versus the billboard.
Test each new component in isolation on a scrap board before integrating into a showpiece. A miswired adder buried inside a mansion wall is a weekend of archaeology. Snap boxed spares in a labeled chest — ferry trips are not free.
Performance matters on busy servers. Gigantic free-running counters updating dozens of displays can hurt client framerate for visitors. Offer a selector-powered “show mode” that sleeps fancy animations until a guest hits a button.
Suggested Learning Path
- Ferry once with a small cash buffer and buy a simple gate plus a display/converter pair (~$3,500 + ~$1,200, confirm live).
- Make a lamp or digit react to a button so you trust the signal path.
- Add a counter that increments on button mash, then display it.
- Introduce a latch to hold a mode bit.
- Only then attempt Binary to BCD chains and ADD3 tricks for multi-digit decimal readouts.
- Graduate to selectors that swap between “price,” “timer,” and “easter egg” screens.
If frustration spikes, go chop Frost for an hour. Logic is richer when your wallet and mood are both solvent.
Frequently asked questions
Where do I buy the new logic items?
At Link’s Logic in the Tropics, reached by paying Hoover for the ferry.
How much are segment displays and converters?
About $3,500 per 7-seg or 14-seg display and about $1,200 per converter in the September 2026 wave — confirm shelf tags in-game.
What do segment converters do?
They sit with the displays (typically one stud behind) so numeric/signal data renders correctly on 7- or 14-segment units.
Do I need logic items to make money?
No. They are builder content. Chop and mill for cash; buy logic when you want showcase systems.
What is Binary to BCD for?
It helps convert binary patterns toward binary-coded decimal pipelines used with human-readable displays.
Where is the focused displays guide?
See the segment displays guide for placement, color cycling, and ferry checklists.
