Using coins you can upgrade your starting vehicle and unlock new ones. You'll quickly realise that to unlock most of the levels and vehicles you'll have to use the in-app purchases to buy coins rather than earning them, but it's perfectly possible to play Hill Climb Racing without spending any money at all.

In this delightful cave flyer, your disgruntled lab-assistant character steals a machine-gun-powered jetpack (don't ask) and takes flight through the lab's never-ending string of long, tunnel-like rooms. As you jet or run along, you need to avoid electrified barriers, lasers and missiles while collecting coins. The mix of responsiveness and acceleration is just about perfect, the comical graphics raise it above most offerings in the genre, and the extras - including a superb array of vehicles - make Jetpack Joyride a true standout.

We've played KANO a bunch of times and still have absolutely no idea what's going on. We know what we have to do, but this is otherwise a game of strangeness.
The gameplay, then, involves colour-matching. You control a platform at the foot of the screen, which has four coloured tiles. It can be spun with a finger, and stops with a prod, in a pleasingly tactile manner. The aim is to match the colour of a bouncing and endlessly transforming gurning 3D being when it lands.
At first, KANO is mind-numbingly easy, but that doesn't last long. Within a minute or so, the bouncing increases to manic pace, and you'll eventually miss a match. At that point, the tile disappears, leaving a hole into a lava pit; you'll then meet a furious fireball, which when it appears must be steered into the lava rather than allowing it to collide with any remaining coloured tiles. Now and again, there's a little bonus section, where you grab coins in space, boosting your points tally.
The game continues until you've only one tile left, at which point you're awarded with a score and get to have a bit of a breather. Rather amusingly, the sole IAP (£2.29 for 'premium') adds a 'turbo mode' at double speed. Frankly, we're not sure we'd be able to cope. Craig Grannell
