What Are the Best Trap Combos in Orcs Must Die! The Board Game?
The strongest trap combos pair a crowd-control trap (something that slows, knocks back, or redirects orcs) with a damage trap placed just behind it, both set at the same chokepoint. Control buys time inside the kill zone; damage spends that time. Placed alone, either trap type does a fraction of the work it does paired with the other.
That's the short version. Petersen Games' own product listing for the game describes the core loop as building "trap combinations" while defending against "increasingly difficult waves." This guide digs into that design space directly: how to combine trap types, hero abilities, and map position into a defense that actually holds through wave ten.
Why Does Combining Trap Types Beat Placing More Traps?
More traps isn't automatically a better defense. A row of five identical traps at five different spots on the map spreads your resources thin and lets orcs pick the path of least resistance. A combo does more with less: two or three traps working together at one chokepoint outperform five scattered ones, because each trap in the combo compensates for what the others can't do alone.
Think of it as division of labor. A crowd-control trap doesn't kill much on its own, but it buys the extra half-second a damage trap needs to hit more targets. A damage trap without any crowd control just clips the front of the line while everything behind it walks through untouched. Neither trap type is weak. They're just incomplete without the other.
How Do You Layer Damage Traps and Crowd-Control Traps?
Order matters. Put the control trap first, in the direction orcs are coming from, and the damage trap second, closer to whatever you're defending. Orcs hit the slow or knockback effect, bunch up or lose momentum, then walk straight into the trap built to punish that exact moment.
Reverse the order and the combo falls apart. A damage trap placed first thins the wave a little, but the orcs that survive hit your crowd-control trap at full spread, with no bunching left to take advantage of. The control effect needs a target group behind it to be worth its resource cost, and that group only exists if control triggers before damage does.
Where Should You Place Traps to Funnel Orcs Into a Kill Zone?
Funneling is the whole game. Because the fortress uses modular tiles, the corridor layout changes session to session, so the "best" placement from last game won't hold up automatically. What stays constant is the principle: find the narrowest, longest stretch of path and build your combo there rather than splitting it across a wider area. One good chokepoint, not five average ones.
A single well-placed combo at one true chokepoint beats the same trap types spread across two mediocre ones. If your fortress tiles create a fork in the road, resist the urge to cover both branches evenly. Pick the branch orcs are more likely to take, or the one closer to what you're protecting, and build your combo where it does the most damage per resource spent rather than trying to defend everywhere at once.
How Many Traps Can You Actually Afford Early in a Session?
Not many, and that's the point. Early waves give you limited resources, which forces a real decision: one solid two-trap combo at your best chokepoint, or several weaker single traps spread around. Take the combo. A defense that's strong in one place beats a defense that's mediocre everywhere, especially while the wave deck is still escalating and hasn't thrown its hardest cards yet.
Upgrade cards change this math as a session goes on. Rather than spending every new resource on a brand-new trap, upgrading an existing trap in your combo is usually the better return, since it improves a piece that's already proven itself against the layout in front of you. Save some resources each round rather than spending them all immediately; that patience is what lets a combo scale with the wave deck rather than falling behind it.
How Should Trap Combos Change Between Minion Waves and Boss Waves?
Minion waves reward crowd control. A pack of standard orcs moving together is exactly what a slow or knockback trap is built to punish, since bunching up a group multiplies the value of whatever damage trap you've paired with it. Lean into control-heavy combos when the wave deck signals a large, low-threat group is coming.
Boss waves flip that math. A single tough target doesn't bunch up with anything, so a crowd-control trap built for groups loses most of its value against it. Damage output matters more here, and this is where hero abilities and spells often do more work than a trap ever could against one high-health target. Read the wave deck before committing resources. A combo built for a swarm and a combo built for a single boss are different tools, and using the wrong one wastes a placement you can't easily take back mid-wave.
How Do Hero Abilities and Spells Fit Into a Trap Combo?
Traps are the static half of your defense. Heroes are the active half, and a real trap combo accounts for both. The Unchained Edition ships with four hero miniatures, each with its own abilities, plus spell cards that give a player an option beyond just watching traps trigger. Station a hero near the weakest point in your combo, the spot where a fast unit or an unlucky roll could slip through, and use that hero's ability to plug the gap the moment it opens.
This is also where a widely shared piece of community feedback is worth knowing before you build your strategy around traps alone. A review of both editions at Just Push Start noted that traps in the tabletop version "play second fiddle to the heroes by a long stretch," landing only a few kills where the video game's traps cut through whole waves. The practical takeaway isn't that traps are a bad investment. It's that a combo built entirely on trap tokens, with no hero backup planned, is leaving your strongest damage source sitting on the sideline.
What Do Reviewers and the Community Say About Trap Strategy in This Game?
Outside opinions back up the core idea here: combos beat single traps, and the game is built to reward planning around the map you're actually given. A hands-on review at RPG.net that played through both the Order and Unchained editions extensively described a Map Book offering difficulty tiers from Beginner up through Hell, meaning the chokepoints and pressure you're planning combos around change by design, not just by luck of the tile draw.
BoardGameGeek's listing for Orcs Must Die! The Board Game is worth a look too, particularly the forums, where players compare notes on which trap pairings held up against specific wave types. Community reporting like this is a good supplement to the rulebook, though it should never replace it. Check the printed rules for exact trap effects and costs before you build a session around any single combo.
Where Should You Start Building These Combos?
Start with the full box. The Orcs Must Die! Unchained Edition at Petersen Games includes everything this guide assumes you have on the table: modular fortress tiles, four hero miniatures with their own abilities, 60-plus orc miniatures, trap tokens, upgrade cards, a wave deck, and 3D door and barricade pieces. Nothing here requires a separate expansion to try.
If you've already got the base game down and want more wave variety to test your combos against, the wider Orcs Must Die! collection at Petersen Games covers the expansion packs built to plug into an existing session.

Frequently Asked Questions
What's the single most important trap combo principle in Orcs Must Die?
Control before damage, at the same chokepoint. A trap that slows, knocks back, or bunches up orcs should trigger before a trap built for raw damage, so the damage trap hits a compressed group instead of a spread-out line. Order and placement matter more than sheer trap count.
Should I spread my traps across multiple corridors or concentrate them?
Concentrate them at your best chokepoint, especially early in a session when resources are limited. A strong two-trap combo in one location generally outperforms several single traps spread thin, since a combo compensates for what each individual trap type can't do on its own.
Do trap combos need to change for boss waves versus minion waves?
Yes. Minion waves reward crowd-control traps, since bunching up a group multiplies the value of the damage traps paired with them. Boss waves involve a single tough target that doesn't bunch, so damage output and hero abilities typically matter more than control effects in that fight.
Are traps enough on their own, or do I need hero abilities too?
Plan on using both. Reviewers who've played extensively have noted that traps alone hit a modest number of targets compared to what hero abilities and spells can do in a single wave. Treat traps as the static layer of your defense and heroes as the active layer that covers whatever the traps miss.
Does the modular fortress layout mean I have to rebuild my strategy every game?
The specific tiles change, so the exact chokepoint moves, but the underlying strategy doesn't. Find the narrowest, longest stretch of path on whatever layout you're given, build a control-then-damage combo there, and adjust based on whether the wave deck shows minions, a boss, or both.
