The AMM Fantasy Collecting Game for the Impressionist & Modern auctions in London is now open.

How does it work? We put together 64 lots from the sales with nearly £200m. You get a budget of £50m to “buy” at the low estimate the works you think will perform best. Follow the results on our scoreboard and, if your collection totals more on hammer price than the others, you’ll win a cash prize. Top ten collections win.

The game closes June 19 at 6pm BST or 1700 UTC.
