Luiten won the last of his six European Tour events in February 2018
World number 98 Joost Luiten claimed a two-time victory in the first edition of the BMW Indoor Invitational.
The 34-year-old carded a six-under-par 66 over the Old Course layout in St Andrews, on his golf simulator.
Former world numbers Martin Kaymer and Lee Westwood also competed virtually in their own home in one round, 18 hole Strokeplay event.
South African Dean Burmester threw his arms in the air to celebrate after a hole-in-one on the par three eighth.
Dutchman Luiten divided his prize of 10,000 euros between his own charity and a hospital in his native Rotterdam.
The six-time European Tour winner made a birdie from the fifth, eighth and ninth hole in a front nine of 33 and took further shots on the 12th, 14th, 15th and 16th with his only bogey of the day on the 18th after not coming up and down from the Valley of Sin.
"You try to keep fit and exercise as you can indoors, but it's different, so it's good to have some nerves and that sense of actually competing and trying to beat everyone, & # 39; said Luiten.
"That is the best thing for us and that is why we are golf professionals. We've missed that feeling for a long time and it was good to get it back and do it right. "
He shot two shots of Frenchman Damien Perrier, who fired seven birdies in his opening 14 holes , but then three consecutive bogeys from the 15th card Bernt Wiesberger in the interactive playgroup
Wiesberger placed the game at par 72 level, the same score that Westwood scored, while Kaymer finished two above par 74.
Another tournament next weekend using the Royal Portrush layout, with further events on the designs at Golf Club Munich Eichenried, Valderrama and Wentworth.
