Pokemon Go servers crashed this afternoon sparking chaos for millions of gamers worldwide.
Players in the UK, as well as Holland and the US, were complaining that the reality game was down and wouldn't allow them to log in.
When users tried to play the game they were greeted by a message that says: "Our servers are humbled by your incredible response. We are working to resolve the issue. Please try again soon!"
The game now appears to be up and running for most UK users.
App developer Niantic said on their website: "Due to the incredible number of Pokémon GO downloads, some Trainers are experiencing server connectivity issues. Don’t worry, our team is on it!"

The Pokemon Go official app later said: "Trainers! We have been working to fix the #PokemonGO server issues. Thank you for your patience. We'll post an update soon."
One devastated user tweeted: "I could definitely leave the house but what's the point if Pokemon go servers are down?"
Tarek Mouganie said: "Been playing #PokemonGo for over two hours, server crashes, I look up and I have no clue where I am. Send for help."
Daniel Jackson tweeted: "So now what? Am I supposed to just walk around a sunny park for no reason? That's disgusting. #PokemonGO"
Another user said: "So far my car has failed it's MOT then Kante leaves us for Chelsea and now Pokemon Go won't sign me in!"
Phones buzz when a creature is nearby and, using the camera, they appear wherever you are, whether it’s a library, shopping centre or supermarket.
The gamer then catches and trains the creatures, which can look like rats, snakes, dragons, birds and eggs.
When running correctly, on a smartphone Go will keep you notified of how far away a nearby Pokémon, rival trainer or group event is.
Players can scan their surroundings while out and about and if they’re lucky, a wild Pokémon might pop up on their screen for them to grab.
They can then throw a ‘Poke Ball’ at it in an attempt to capture the Pokémon and add it to their collection.
