The short version: The Google Halloween Doodle game with Momo the cat is a 2016 interactive doodle where you play a magician cat casting spells to light lanterns and battle other wizard cats, and it is still one of the best free case studies in seasonal engagement marketing you will find. You don't need to be Google to borrow what made it work: a tiny, repeatable game loop, a character people like, and a willingness to publish something fun instead of something "on brand."
What the Momo the Cat Doodle is
Google released the Momo doodle on 31 October 2016. It is a multiplayer-style game built from five chapters, each one opening up as you complete the last. You play a witch cat called Momo who competes against rival cat wizards in a tournament. Each level is a quick mini game, things like matching lantern colours, racing through an obstacle course, or casting a spell before time runs out, and finishes in under a couple of minutes.
It was playable directly from the Google homepage on Halloween, and it still turns up every year around 31 October when people search for it, because Google has kept the game archived and playable through the Google Doodles archive rather than deleting it after one day.
Why this one doodle outperformed almost every other Halloween campaign that year
Most brands treat Halloween as an excuse to slap a pumpkin on their logo for 24 hours. Google did something different: it built a genuine five-level game with a consistent character, a clear win condition, and an ending. That is the uncomfortable bit nobody running a "fun seasonal campaign" wants to hear: a static graphic with a spooky filter is not content, it is decoration. People share games, stories and characters. They do not share pumpkin clip art, no matter how on-trend the orange is.
If you strip away the cute cat, the Momo doodle is a product launch with a deadline. It had:
- A single clear mechanic repeated across five short levels (not five different games, one game with escalating difficulty)
- A character with a name and a personality, not a generic mascot
- A natural end point, so players felt finished rather than endlessly scrolling
- Zero sign-up, zero download, zero friction, you played it on the homepage you were already on
That last point is the one small businesses miss constantly. The doodle worked because the barrier to entry was nothing. Compare that to the average "Halloween giveaway" that asks someone to follow three accounts, tag a friend and fill in a form before they even see the prize. Friction kills seasonal content far faster than a bad idea does.
A worked example: what a small business version of this looks like
Say you run a local garden centre with an email list of 4,000 people and a modest Instagram following. You are not building a five-level browser game, obviously, but you can copy the structure.
Here is a version that would realistically take one person about six hours to build in a tool like Canva and a simple quiz plugin:
- Pick one character, not a theme. Instead of "spooky plants," invent a single recurring mascot, say a pumpkin called Pip who appears in every piece of content that week.
- Build one short, repeatable interaction. A five-question "which spooky plant are you" quiz, each question taking under ten seconds, mirrors the doodle's short-level structure.
- Give it a visible finish. Question five ends with a result, a discount code, and a one-line call to action. No endless scroll.
- Remove every piece of friction you can. No account creation, no app download. Link straight to it from your email subject line and Instagram bio.
- Run it for exactly one week, 25 to 31 October, then archive it rather than deleting it, the same way Google kept Momo playable year after year. Content with a shelf life past its launch week is content that keeps earning without you doing anything.
If that quiz gets a 12% click-through from a 4,000-person list, that's roughly 480 people playing something, far more engagement than the same list will give a plain "Happy Halloween from us all" email, and it costs you an afternoon, not a developer budget.

The part that makes marketers uncomfortable
Here's the bit people avoid saying out loud: the Momo doodle worked partly because Google can afford to throw away a game after Halloween and nobody minds, while most small businesses are too scared of "wasting" content to ever make something this light-hearted. You don't need permission to be playful, and you don't need to measure every seasonal post against your core brand message. A fun, disposable, slightly silly piece of content that gets shared is worth more in October than another polished carousel nobody screenshots. The businesses that win seasonal attention are the ones willing to look a bit daft for a week, not the ones protecting their "tone of voice" document.
What to take from this if you run a small business
If you want to use the Momo doodle as a template rather than just a nostalgia trip, keep three numbers in your head: one character, five steps maximum, one week of life. That's it. Anything more complicated than that and you're building a product, not seasonal content, and products need real briefs, budgets and testing timelines, not a Tuesday afternoon.
If seasonal and gamified content keeps underperforming for your business and you're not sure whether the problem is the idea or the execution, that's exactly the kind of thing worth a short session with an AI consultant for small business who can help you build a repeatable content system instead of reinventing it every October.
Frequently asked questions
Can you still play the Google Halloween Doodle game with Momo the cat?
Yes. Google keeps past doodles, including Momo, playable in its Doodle archive, so you can find and play all five levels outside of the original 2016 Halloween release date.
How many levels does the Momo cat Halloween Doodle have?
It has five levels, each a short mini game lasting roughly one to two minutes, building toward a final showdown between rival cat wizards.
Why did Google choose a cat wizard for a Halloween doodle?
Google doesn't publish exact creative briefs, but the format follows a pattern you'll see across its interactive doodles: a simple, likeable character and an easy game mechanic tend to get shared far more than a static graphic, which is likely why a playful character like Momo was chosen over anything more literal or seasonal-cliché.
Can small businesses copy the Google Doodle game idea for their own marketing?
Yes, on a much smaller scale. The structure worth copying is one clear character, a short repeatable interaction such as a quiz or spin-the-wheel, zero sign-up friction, and a defined end point, all of which can be built in an afternoon using simple quiz or email tools rather than custom game development.
