WEEKEND PROJECT
$3K/Month From a 3-Day Wordle Clone (4 Years Later)
π KLaci, a Budapest-based dev and movie nerd, writes about a side project he almost killed in its first weekend.
In March 2022, riding the Wordle hype, he built Actorle β a guess-the-actor daily puzzle β in 3 days.
Launch went badly...
I posted on Reddit and a few forums. Two of the top comments were "insanely hard to win" and "literally unplayable", the second one because I'd forgotten to add John Hurt to the database.
I almost killed the project that weekend.
A tiny British humor newsletter featured it next. Then he added the feature that changed everything: a "share your score on Twitter" button.
Virality has to be designed in.
The Wordle-style shareable score grid is what carried Actorle. Without that one feature it would've died in week 2.
Mashable picked it up. Accounts with 10K+ followers started posting their grids π
Four years later π
~10K daily active users
~$3K/month from display ads
A small portfolio of spinoffs
Very low maintenance
His pitch to other indie devs...
'Build a B2B SaaS' isn't the only indie path.
A low-maintenance daily consumer game is a real business too.
You could vibe-code a Wordle-for-X this weekend β sports, music, anime β using a free public API for the data.
Just don't ship without that shareable score grid π
AI NEWSLETTERS
He Built 350+ AI Local Newsletters β Then Got Acquired
π Matthew Henderson built an AI newsletter so his grandparents could keep up with their hometown.
Then he scaled it.
By early 2025, his network Good Daily was running 350+ daily local newsletters across 47 states. All AI-driven π€
One person at the controls.
In July, 6AM City β the biggest US local newsletter publisher β acquired Good Daily and made Henderson VP of Engineering.
π He'd added 500K+ subscribers in under a year, with markets as small as Rock Springs, WY (pop. 20K).
It's also reshaping how 6AM City scales.
From a recent podcast, COO Ryan Heafy laid out the math π
For a quarter million dollars, I can go turn on a city... be live in 90 days and be profitable in two years...
β¦now I can be up and running in one day and be profitable in two days and be in any city we want to be in.
Pick a small town nobody's covering and spin up your own AI-driven daily digest, monetized via local ads π€

POINTS GUY
$231K From a Credit Card Side Hustle Nobody's Touching
Colin Stroud spent a weekend learning credit card rewards.
A year later, he apparently cleared $231,000 β on about $100/mo in software, no ads π€―
He's a rewards consultant. He sits with small business owners, looks at what they already spend, and rebuilds their card setup to earn 2.5β3% back instead of 1%.
His own parents ran their medical practice on a 1% cashback card, spending $40K+ a month. Colin reworked it and saved them over $20,000 in travel.
A contractor dropping $60K/mo on materials earns just $600 back at 1%. The right cards bump that to $1,800.
Colin charges $875, one time, to set it up β recouped in weeks.
The gap nobody's filling: every "points" blog out there is written for travel hackers. Nobody's sitting down with the plumber or the dentist π
He lands clients posting daily on LinkedIn, where this niche has almost no competition π₯
And you don't need to have visited 60 countries β just know more than your client. A free course at The Daily Drop plus a tool like Seats.aero gets you most of the way there.
Pick one type of business owner β dentists, contractors, restaurants β and become their points guy π
