How it plays

A simple board with a real rental business underneath

🎲
Claim areas, charge fees
16 neighbourhoods. Control the turf and rivals pay you every time they land. Those fees only grow.
🔨
Fight at auction
Units, buildings, owner mandates, permits, and the carcasses of bankrupt rivals.
📉
Outlast the market
A market-cycle deck tightens every month: rates, crackdowns, funding winters, consolidation.
💀
Bankrupt them all
No points, no final score. The last solvent operator standing takes everything.

Why I built this

I have been obsessed with property since I was a child, and it started with a board game. The little houses, the rent you collected when someone landed on your square, the gamble of when to buy and when to hold. It taught me, years before I understood it, that property is really a game of cash flow, timing and nerve.

I have spent most of the last fifteen years living that out for real. I listed my first flat in Istanbul in 2010. I built Erasmusinn, a student-housing marketplace that grew to around ten thousand rooms. I bootstrapped Oval Experiences and ran about sixty short-let apartments, where I learned the hard way how quickly an operation falls over when it depends on people remembering everything. With Fullog I took the same playbook into fulfilment, arbitraging space and running the logistics on top of it. Today I am building Cendra, putting AI to work on the messy, human side of running rentals.

Rental Rush is all of that, distilled into a board game. Every mechanic comes from something I have actually felt: the void period in low season, the owner who wants paying on time, the licence that drags on for months, the building lease that bleeds you before it earns a penny. It is a small love letter to the operators who keep the lights on, and an experiment in how much real operating intuition a simple game can carry.

It's open source. Make it better.

I built this in the open and put the whole thing on GitHub under an MIT licence. The game engine is pure TypeScript with its own test harness, so you can change the economy, add event cards or build a smarter rival and prove it still holds up. Pull requests, ideas and bug reports are all welcome.
