More than 120 million people have played the original Crossy Road game, including plenty of kids. Now there’s a new version: Disney Crossy Road.

You can probably guess the main difference. While the gameplay – hop and swipe your way across roads and rivers without getting squashed – remains the same, there’s a famous cast of characters to play with.

Well, I say ‘famous’ – part of the fun of Disney Crossy Road is that it doesn’t just focus on the most familiar Disney and Pixar stars, but also some of the less well-known characters.

There are more than 100 to play as here, grouped into categories including Mickey and Friends (classic Disney cartoon stars), Toy Story, Inside Out, Wreck-It Ralph and The Lion King.

(Sorry, no Frozen, or Monsters Inc, or… Well, clearly there is scope here for more films and characters to be added in the coming months, in the same way that the original Crossy Road has received regular updates with new characters.)

The levels change according to the character being played, from familiar cars for Mickey and Friends, to the pride lands of Africa for the Toy Story characters – compete with stampeding wildebeest – Al’s Toy Barn, San Fransokyo and the Haunted Mansion.

Playing the game is simple: you tap to hop forward a step, and swipe to move left and right. We’ve seen children as young as four playing the original with no problems, even if they lack the fine-motor skills to survive for long.

That’s one surprise about Disney Crossy Road: you really can splat Mickey Mouse into the side of a lorry when mistiming your moves. While it’s a cartoon flattening rather than anything more gory, it’s worth remembering if you have a sensitive young child who might be upset at causing a squashed Mickey, Simba or Buzz Lightyear.

Like its predecessor, Crossy Road is free to download and play. You start with only one character – Mickey Mouse – but new characters are unlocked via an in-game prize machine. It costs 100 of the game’s ‘coins’ currency and spits out a random character for the collection.

Those coins can be picked up while playing – they’re dotted around the levels – while every so often the game presents a free gift, which can be as few as 20 coins, or more than 100.

Coins can also be earned by watching 30-second advertisements, which at the moment all seem to be for other Disney apps. What all this means is that kids can play Disney Crossy Road completely for free, unlocking a big collection of characters without paying.

But… if they’re keen as mustard to get one particular character, you can buy it using an in-app purchase: they cost £0.79, £1.49, £2.29 or £3.99 depending on the rarity of the character, with most falling into the first two of those prices.

The game is very fun: We think Disneyphile kids will love it, and a fair few parents too. Disney Crossy Road is a free download for iPhone and iPad, and a free download for Android.
