Jake Shaw, 21, died after falling from the upper floor of the Scout centre in the Swiss Alps where he had been volunteering as a climbing instructor . A popular  graduate fell to his death from a bedroom window in the Swiss Alps after playing drinking games, an inquest heard. Jake Shaw was just beginning his gap year - volunteering as a climbing instructor at Kandersteg International Scout Centre - when the tragedy occurred last year. The 21-year-old had fallen 25ft (8m) from the upper floor of the building in the early hours of August 1. He was airlifted to hospital in Bern suffering severe injuries but died nine days later. Lincoln Coroner's Court heard that shortly before his death, Jake had been celebrating the Swiss National Day with friends with drinking games called 'Power Hour' and 'Ring of Fire.' After consuming a large amount of beer in the staff room at the centre he returned to his room at around 2.45am in a 'very drunk state'. It is then believed he lost his balance as he tried to open a bedroom window and toppled out of the window at the adventure camp in Interlaken, Switzerland. Today Lincolnshire Central assistant coroner Paul Smith, concluded that Jake's death was an accident. He said: 'The level of alcohol in his body was consistent with 11 standard drinks. 'It's the presumption that he was undeniably very drunk that evening - how that affected his balance is a matter of speculation. 'The most likely explanation is that in his state he took himself to bed, opened the window and perhaps overbalanced and fell. 'I'm satisfied that this was a tragic accident.' The court heard how in the game 'Power Hour', participants have to drink a shot of beer every minute for an hour and if completed two and a half litres of beer is consumed. A police report read out during the inquest, added: 'Examinations indicated that the August 1 celebrations were followed by a private party which Jake had attended. 'There were group games with drinks in the staff room. Jake had probably drank a large amount of mainly beer. After consuming a large amount of beer in the staff room at Kandersteg International Scout Centre he returned to his room at around 2.45am in a 'very drunk state'. Shortly before his death, adventure-loving Jake had been celebrating the Swiss National Day with friends with drinking games called 'Power Hour' and 'Ring of Fire' 'At some time after 2.45am he came away in an alcoholised state without letting anyone know where he was going. 'It must be presumed he returned to his room. How the fall happened can't be established in any detail.' Jake, from Welton, Lincolnshire had graduated with a maths degree from Sheffield University and had just started a gap year at the time of his death. The keen mountaineer and skier was planning to spend the winter season in the nearby French Alps. His devastated parents, Ian, 51, and Fiona Shaw, 52, wrote a joint statement about their son which was read out during the inquest. In it they said: 'Jake was intelligent, reliable, easy going and a loveable young man. He loved life, his friends and his family, and his passions were music and climbing. 'He had plans for next year mapped out to live life to the full . 'We are happy he was having a great time in the place he loved.' Jake, who loved the outdoors, was just beginning his gap year by volunteering as a climbing instructor when the tragedy occurred . The keen mountaineer and skier was planning to spend the winter season in the nearby French Alps before his tragic death . At the time of his death mother Fiona, a speech and language therapist, said: 'Jake was very gifted, the best son in the world who became my rock - he was dependable and made me laugh. 'He was intelligent and very funny, with a dry sense of humour. 'Although Jake was taken from us at only 21, they were great years and Jake was fortunate to have had so many marvellous experiences and done so much in his life.' Ian, a human resources manager, added: 'We are a very close family and we are all so proud of Jake. 'The countless messages we have received from his wide circle of friends have made us realise just how popular and loved by others he was. 'Jake was an avid reader and he really knew what was going on in the world.. He followed loads of sports, especially football, cycling and cricket. 'He did things I never achieved through his mountaineering trips abroad and we followed his achievements with pride. I'll really miss going out walking and climbing with him.'
