BÚNKER 7 — Escape Rooms, Santa Cruz de la Sierra, Bolivia.
The problem: Mariana designed all four rooms herself and runs them with two part-time gamemasters. Her personal phone is the booking desk. Every inquiry lands on WhatsApp, peaking Friday 19:00–23:00 — exactly when she's inside a room and can't look at her screen. Twelve hours a week gone, and 24% of weekend sessions still go empty.
What I built: an escape room booking system where the inquiry never happens. The customer picks a door, picks a time, confirms. Three taps, forty seconds, instant confirmation with a sealed case code. Zero actions from the owner.
The part nobody models: the 20-minute reset. Every room has to be rebuilt between groups, so one booking occupies 80 minutes of calendar, not 60. Booking 19:00 blocks the room until 20:20 and the next offered slot is 20:30 — never 20:00. Blocked windows stay visible, labelled IN PLAY and RESET IN PROGRESS with diagonal hatching, so the customer understands the constraint instead of hitting an invisible wall. This is the exact mistake Mariana made every Friday, booking back-to-back from chat and then running.
Also: real .ics download, a group link where each player confirms attendance without an account, automatic reminders at 24h and 2h with one-tap reschedule, and a waitlist that reassigns a freed session on its own.
The operations terminal quantifies the win in the owner's own language: "Hours of WhatsApp saved this month." Not a vanity metric — confirmed bookings × the 9 minutes each one used to cost her.
Craft notes: a cinematic bunker corridor where each of the four doors is a different object — a riveted Soviet blast door, a chipped enamel asylum door, a carved stone crypt slab, a hazard-chevron airlock — and each room page has its own art direction inheriting that door's light. Bilingual EN/ES. No placeholder states anywhere: if a panel had no real data, I didn't build it.

Day 3 of working on my project for the Lovable Challenge.
And somehow, almost one full day of those three went into the intro you see when the page first opens.
Not because it was necessary — mostly because I’ve wanted to try something like this for a long time.
Web design and development are far from my main field, so I kept putting this idea off. This challenge finally gave me a reason to test it properly — and seeing it actually work is ridiculously satisfying.
The video was converted into an image sequence and tied directly to scrolling on desktop and swiping on mobile, so the animation is controlled by the user as they move through the page.
Right now the project is already at Build 4.2.3.
The backend is working properly, the main mechanics are in place, but visually… there’s still a lot to redo. The current plan is to rebuild almost the entire visual layer before the final version.
I also found out today that Lovable reduced the number of prize spots quite significantly — apparently, there will only be 3 finalists.
That definitely makes the odds a little more painful 😅
But either way, I’m already getting a new portfolio case out of this project, and I’m finally experimenting with things I’ve wanted to build for a long time.
How’s everyone else doing?
Still working on your project, or have you already submitted it?
Or did you decide not to participate at all? If so, I’m curious — what made you skip it?
What I Built
I built Glow & Grace, a self-service booking website for a solo, home-based nail studio in DHA Phase 5, Karachi. Clients can view services and prices, pick an open time slot, and get instantly confirmed — no messages exchanged with the owner. The owner has a simple dashboard where every booking appears automatically, along with deposit status, so there's no manual confirming or texting required.
Why I Built It
Solo, appointment-based businesses like small nail studios, salons, and home-based service providers often run entirely on WhatsApp. The owner is doing the client's nails with one hand and replying to booking messages with the other — checking availability, confirming times, and texting reminders, all manually. This doesn't scale, wastes hours every week, and leads to double-bookings or missed messages. I wanted to solve the actual bottleneck: turning "can I book with you?" into "you're booked" without the owner lifting a finger, while also addressing the no-show problem with a small deposit built into the booking flow.

I love the color style
Submitted my first Lovable entry today and got already my first visitors. Thank you for exploring its features. Made my day! 😊
This is nice @Benjie Balais
