Cosmic Frog Review – Punching Space Toads into the Aether

Ever wanted to play something that feels like a drug-fuelled fever dream in board game form? This is it. Cosmic Frog, designed by Jenna Felli, is like nothing you’ve played before. You’re playing as two-mile-high immortal frogs, hopping around the cosmos, devouring chunks of a shattered world and eventually coughing them back up for points.

It’s packed with dice rolling, frog-on-frog clashes, and plenty of chaotic movement as you leap across floating terrain, dodge splinter strikes, and scoop up as much land as you can get your tongue on. The artwork matches that psychedelic energy beat for beat. It’s loud, strange, and completely unapologetic about it.

So does all that chaos actually come together into something worth playing? Let’s find out.

How to Play

Life is tough when you’re a giant frog whose sole purpose is to collect terrain from a shattered world. It’s even tougher when every other frog at the table is trying to do the exact same thing. Still, a job’s a job, and if you want to win, you’ll need to harvest, fight, and steal as much terrain as possible.

Before diving in, Cosmic Frog does itself no favours when it comes to rules clarity. To fully immerse you in its world, or I guess outer-world, it ditches familiar board game terminology and replaces it with its own brand of cosmic language.

For example, what you’d normally call mana is known as Oomph. I’ll do my best to translate as we go, but I’ll probably slip between terms here and there. Sorry in advance.

The game runs on a turn order deck. Each round, every player has six action cards shuffled into it, but you never know when yours will come up. When it does, you only get a single action. Although, you can spend two mana to take an extra action, but that’s it.

Each player also has a unique frog ability card, which gives you a passive bonus and defines how you handle combat.

Now, since Cosmic Frog takes place in Dimension 0, your frog can exist in three different locations, and where you determines what you can do.

If you’re on the Shard, the floating remnants of the shattered world, you can:

• Leap to another Shard tile. The distance depends on how many tiles your frog is currently holding.
  • If you land on another frog, you immediately attack them.
  • If you leap off the Shard, you end up in the Aether, or you can pay one mana (Oomph) to Slipstream to another edge instead.
• Harvest the terrain tile you’re standing on.
• Recover and regain all your spent mana.

If you’re in the Aether, or the space between the Shard tiles, you can:

• Descend back onto the Shard at any edge.
• Disgorge, placing all your collected tiles into your vault to lock them in for end game scoring.
• Attack another frog in the Aether.

The third location is the Outer Dimensions. You only end up here if you lose a fight in the Aether, and it’s not a great place to be. Your vault can be raided, and instead of taking normal turns, you roll a die and slowly make your way back to the exit.

When combat happens, as it often does, both players roll dice based on their frog’s abilities. You can spend mana to Overpower, rolling two dice and taking the higher result, or Boost for a flat +1. The attacker needs to beat the defender’s total to win.

If the fight happens on the Shard, the attacker either steals tiles from the defender or takes a free harvest action, while the loser gets launched across the map like they’ve just been punched out of a Dragon Ball Z episode.

In the Aether, the stakes are higher. Lose a fight there, and you’re sent straight to the Outer Dimensions.

The game keeps ticking along like this, but there’s always a bit of tension sitting in the turn order deck. From the second round onwards, a Splinter Strike card is shuffled in, and when it appears, a meteor slams into the Shard and starts tearing it apart. As pieces break away, you flip those tiles over, sometimes revealing larger cracks that push the Shard closer to collapse.

Once the Shard finally shatters, or there’s no land left to harvest, the game ends. You tally up everything stored in your vault based on the scoring rules, and whoever’s collected the most valuable haul wins.

Dimension Zero: Where Strategy Goes to Die

Cosmic Frog is a game that puts theme first, and when the theme is this unhinged, you know things are going to get wild. Randomness isn’t just part of the experience, it’s sown into the ground and farmed for its bounty.

That can be a hard sell if you enjoy carefully planned strategy. But if you like living on the edge, where you have no idea what your next turn will look like or even when it will happen, then Cosmic Frog was made for you. It can definitely be frustrating if you take your giant space frogs too seriously though, so it’s best to approach it with a pinch of salt. Or maybe don’t, because, you know… we’re frogs.

More than once, I lost a game purely through bad dice rolls, burning turn after turn on combat that went nowhere. But it’s not just the dice that can betray you. The length of the game is just as unpredictable, hinging on Splinter Strike cards showing up and shattering the Shard. That might happen early, it might take ages, or it might drag on longer than anyone expects. The game also isn’t interested in letting you neatly wrap up your plans, so you can be halfway through pulling off your greatest manoeuvre only to have it cut short by a flaming meteorite.

The turn order deck adds another layer to all of this. Sometimes you’ll get back-to-back turns and feel unstoppable. Other times, you’ll be sitting there wondering if your cards were accidentally left in the box. Out of all the randomness, this was easily the most divisive part at our table.

Personally, I loved it. It creates this spark of spontaneity where every turn feels like an opportunity, and when it’s not your turn, you’re fully invested, just willing your next one to show up. Not everyone felt the same though. Some players really bounced off the lack of rhythm, especially since it makes forward planning that much harder.

Then you’ve got Aether Flux cards mixed into the deck as well. When one appears, you can either spend mana to hold onto your current ability or swap it out for a random new one. This is one bit of chaos I genuinely enjoyed, because it forces you to adapt and rethink about how best to use your new ability.

So when you add it all up, game length, turn order, combat, and even your powers are all driven by randomness. Which sounds like a recipe for frustration. But somehow, against all known logic, it all just about works. It feels like it’s being held together with sticky tape and pure commitment to the theme, yet that same theme makes everything you do more fun than it has any right to be.

The Hurdle Before the Hop

Now, while the game itself is a lot of fun, everything leading up to that first turn really tempers the experience.

It starts with the rulebook, which doesn’t do you any favours. The structure is clunky, and the writing leans heavily on its own strange terminology. Words like Oomph, Gullet, Disgorge, Leap, and Shard sound great for theme, but they make the game harder to learn than it needs to be. It’s definitely one I had to read through multiple times before it properly clicked.

Then I had to disgorge all of that information to the rest of the table, which I’m sure only muddied things further.

There are also a lot of specific rulings to keep track of. Do something on the Shard and it works one way, do that same thing in the Aether and it works differently. That constant if-then logic meant I was diving back into the rulebook more often than I would’ve liked, and it’s not exactly laid out in the most helpful way.

Setup doesn’t help either. You’re placing over 100 hexes onto the play area, and to get it looking right you’ll want to line each one up with the printed grid. It takes a while. There’s something oddly calming about it once you settle in, like an extremely nerdy zen garden, but it’s still a hurdle. It does go faster if everyone chips in though.

All of this is to say my first game of Cosmic Frog sucked.

But I’m glad I stuck with it, because every game after that got better. The rules started to click, the terminology stopped getting in the way, and even the setup shifted from frustrating to something a bit more meditative.

Once you’re over that hump, there’s a genuinely fun game here. It’s highly tactical in the moment, constantly asking you to figure out the best move right now rather than five turns ahead. You’re managing your Oomph, picking your fights, and making the most of some really fun movement options.

So yes, between the weird terminology and the drawn-out setup, that first game can be rough. But stick with it, and it starts to reveal why people love throwing giant frogs around the cosmos.
