Wombats are herbivorous solitary nocturnal mammals native to Australia, and — here’s the part you knew was coming; nay, hoped was coming — they poop in cubes. And stack them. Why? I dunno. Darwin was pulling a goof that day.

Now Wombat Poo is a stacking board game by Phil Walker-Harding. Why? We know why. Because poop is funny, that’s why. But is Wombat Poo funnier than its opening joke? I think so. A little bit.

This is exactly what wombats do. Exactly.

On a surface level, Wombat Poo is about stacking cubes. There are three sizes included in the box: small, smaller, and smallest. Maybe that sounds like a complaint. To be sure, I’ve dinged certain dexterity/stacking games in the past for featuring such light components that their edifices collapsed at the slightest exhale, never mind a hand tremor. Fortunately, while the cubes in Wombat Poo are quite small, they have enough heft that the tower isn’t doomed past its first inch. Not right away.

But what makes Wombat Poo function isn’t its stacking. I mean, yeah, without the stacking there isn’t a game. But the stacking is really the backdrop for a compelling system of wagers. Basically, when your turn rolls around, you decide whether to poo or wipe. Each player even gets a double-sided card for announcing their position on the matter. If you poo, that means flipping a card from the deck to determine which size of poo you must stack. If you’re unlucky, maybe you’ll even need to stack two poos.

I imagine that wombats, since they’re herbivores, produce poop that can be composted without bacteria-killing hot methods, but don’t take my word for it. No, really. Don’t take my word for it.

The other option, wiping, backs you out of the round, while also scoring a point for every cube in the stack.

This is unexpectedly clever for a game that might otherwise seem somewhat single-ply. The thing, you see, is that your fortunes aren’t entirely based on your own prowess at squattie-piley. The decision to stay in the round is also an investment in the other players at the table. If someone in your group suffers from the shakes — as does one of my oldest friends and game-night regulars — they might still remain competitive, building their score by surviving their occasional, um, movements, and letting others do the bulk of the hard work. Conversely, their natural weakness at dexterity games may well translate into everyone else’s natural weakness as well. When the tower topples, the player who did the toppling loses two points. A meager sum. Just enough to prevent somebody from overturning the tower out of spite. But when that happens, those who stayed in the round score nothing at all. It’s only by wiping in time that you’ll accrue a winning score. How’s that for a rule to live by?

This transforms Wombat Poo into a surprisingly forgiving experience. Its central question isn’t “Can you stack this?” so much as, “Can you stack this, plus can the next couple of players also stack their cubes atop your wonky-ass placement, so you can get out while the getting’s good.”

Which is a considerably more interesting question than those posed by most stacking games. For adults, anyway.

My six-year-old’s review: bees are better than Wombat Poo.

At the risk of sounding highfalutin’ — not to mention deeply unserious — Wombat Poo proved too subtle for my twelve- and six-year-old children. An unexpected outcome, given the game’s cartoon wombat and topicality. Those kids were cracking poop jokes literally the evening before we broke out the game for the first time. Then, somehow, overnight, they went from “Poop is the funniest thing in the universe” (juvenile) to “Poop is not funny at all” (adolescent), without quite reaching “Poop is funny unless it’s awful, then it’s even funnier” (mature).

There were other factors. The smallest of the cubes were a bit too light for the six-year-old’s fingers. Maybe it doesn’t help that the notion of playing with one’s fecal matter had been painstakingly ingrained as taboo for years by yours truly, lest this leaking ship we call a home tip over the edge into total disaster. And, yes, the scoring wasn’t quite as immediate as that of, say, Rhino Hero.

Look, I know how I sound. Arguing that Wombat Poo is a mature game for adults isn’t really what I’m trying to say here. I’m sure there are sufficiently advanced children who can also manage it, and some of them will have sufficiently arrested parents to stack poops with. I hope so. In my experience, though, Wombat Poo has become an adult filler, a strong contender for those moments when you just want to heap up some cubes, but with more to the rules than penalizing whichever player makes the tower plunge.

The Leaning Tower of Poopa.

In other words, Wombat Poo is the thinking man’s poop-stacking game. Not David Hume level or anything. Voltaire, though? Yeah, Voltaire might stack some poops.

And that’s all there is to say about that.
