X as in eXtra large. In LEGO® X-TREME everything is faster, bigger and even more action-packed. Speedy racers can show they've got what it takes when speeding over the water in the Aquazone Wave Racers. The very brave can also volunteer as test drivers for Project X - LEGO Test Track, our high-speed coaster that is eighteen meters high. At the LEGO MINDSTORMS Centre clever brains may program LEGO robots themselves and then test them in competition with others. Another highlight are our 4D-Movies in the LEGO Studios with a lot of surprise effects.
