Draw Protector

You have one line and limited ink. The physics decide whether what you drew actually holds.

This one earned the most campaigns of anything in the set — twelve rounds of testing, and the largest creative library, which is why three of them are here.

On Google Play

It shipped on Google Play, where the listing read:

Draw lines, Fire, balls and gas to save the hostages

It is no longer listed there.

Where it came from

Built by me — Mohammad Oumari — and taken into testing with Homa, the hyper-casual publisher. The model was volume: build a mechanic quickly, put real user-acquisition spend behind it, and let the market decide within a couple of weeks.

Most prototypes do not survive that, and this one is here because the work is worth keeping, not because it became a hit. The footage is the ad creative as it actually ran — caption bar and all.
