My kids loves Block Blast, so I decided to try making my own version for them.

It's not perfect but it was a fun experiment. My kids weren't impressed. Tough crowd.

Kids are the harshest QA you can hand a puzzle game to, and they reject on feel long before they reject on difficulty. Most homemade Block Blast clones get the rules right and still feel wrong, because the piece follows the finger instead of the grid and the snap lands late....

Patitas & Tijeras: from "can I book?" to "you're booked" for a solo dog groomer in Lima One-line problem: Mariela grooms one dog at a time in Surco, Lima, and loses about 2 hours a day on WhatsApp while 1 in 5 clients never show up.

THE BUSINESS Patitas & Tijeras is a one-woman grooming studio in Santiago de Surco, Lima. Its quirks shape the whole product:

One dog at a time, never in a cage, so the calendar can never double-book

Slot length depends on the dog: a chihuahua takes 45 min, a matted golden takes 3 h

15 protected minutes between dogs to clean the table

Saturdays fill first; weekdays have room

Clients pay a deposit by Yape (Peru's most used payment app) to hold a slot The business is fictional. The problem is real for thousands of small shops in Lima.

FOR CLIENTS

Book in about a minute: breed, size and coat set the exact slot length, so only times that really fit are shown

A Yape deposit holds the slot. A booking can't be confirmed until the deposit arrives

Every booking gets its own page with a QR code and clear next steps

Waitlist and reminders; returning clients are recognized by phone number

Spanish and English, detected automatically

FOR MARIELA

Inquiry inbox: "got a slot Saturday?" gets real times back in one tap

QR check-in on arrival, with clear warnings for codes from another day, cancelled or already used

Regulars with no no-shows in the last 90 days can rebook without a deposit

A dashboard with revenue, occupancy, no-shows and hours saved

In the demo data, no-shows drop from 21% to 4%

HOW IT'S BUILT Built entirely in Lovable on Lovable Cloud (Postgres, auth, storage): 21 versions in about 18 hours. Overlapping bookings are blocked by the database itself, not just the interface. Most fixes came from testing it on my phone as a real client would.

How does the app know a Yape deposit has arrived before it confirms the booking? Does Mariela confirm it from her phone, or does the app read the payment itself?
