Casual games are often called "time-wasters." Not this one.
Play to Cure – Genes in Space puts you in the cockpit of a spaceship, flying through asteroid fields in a bid to collect as much "Element Alpha" as you can. So far, so familiar – but the route you're following is based on genetic cancer data.
By playing, you're helping to analyse genetic data, speeding up the process of identifying faults in the data and helping to advance cancer research. Not bad for a few minutes' casual gaming.

The game itself is pretty basic; you're presented with a map showing concentrations of Element Alpha, and plot a route between the densest pockets of the space dust. Then it's into your spaceship, where you attempt to follow the course you've mapped, flying between waypoints and zapping asteroids.
Levelling up is based on how much Element Alpha you've scooped up; between missions you can sell your cargo to upgrade your spaceship.
