About
Hammy is a tiny hamster with a big job: his wheel powers a cozy retro radio. As long as he runs, the music plays. When he gets tired, the radio grows quieter and static creeps in – and when he falls asleep, it goes silent. Feed him and the music comes back.
HAMMY ON YOUR LOCK SCREEN
• Hammy, his energy and the radio at a glance – on the Lock Screen and in the Dynamic Island
• Feed him right from the Lock Screen, no need to open the app
• Switch his food or one of up to three saved looks there with a single tap
• Optional Lock Screen scenes: starry night, cherry blossom, beach, winter forest and autumn leaves
A COZY IDLE GAME
• Hammy earns coins while he runs – 25 % more while you listen along
• Basic food, treats and super-foods; every day he has a favorite that gives extra energy
• Decorate his room and dress him up: nightcap, tiny sunglasses, knitted scarf, wheels and radios in new woods, string lights and more
• Visitors: a dog runs for Hammy for an hour, and now and then a rare capybara waits on the windowsill
• The seasons change outside the window
• 100 achievements to collect
• Day and night follow the real sunrise and sunset in your city
RELAXED AND FAIR
• Turn the radio off and Hammy takes a break – his energy stays where it is
• No ads, nothing random to buy
• Optional purchases: coin packs, a supporter pack, Lock Screen scenes and pillows for Hammy. Everything else in the shop can be earned with coins from playing.
The radio plays internet radio: channels from a German kids' and family radio station, plus Games Radio with video game music. You need a connection to listen.
Available in English, German, French, Italian, Spanish, Portuguese (Brazil), Japanese, Korean and Traditional Chinese.
