At 10 Euros a pop, he's made 2 566 780 Euros on that game, 65 140 of which was in the last 24 hours (at time of writing). Lately it has been accelerating. Yesterday he had made more than 80k in the previous 24 hours, but a lot of server downtime last night probably affected the night's sales.
Also, he developed it for about a week before it was publicly available in its first form (albeit free and much simpler).
In regards to that 600k at the end of the Wikipedia article that Paypal had frozen -- people were wondering why he left so much in his Paypal account, but he responded was emptying it every week, and sales had just spiked.
