Big Blue is a favourite circuit of mine. It is set on a planet made up
almost entirely of water. It is fairly simple and can be taken, with
practice, entirely flat out. The corners are all fairly easy,
but through the last 2 corners a new hazard is introduced: the
anti-magnetic coating which causes your car to slide out of control.
Go flat out through turns 1 to 4. On the exit of turn 4, just before
meeting the straight with rough on either side, use your turbo and
cut across the rough on the insides of turns 6 and 7. Go flat out around
turns 8 to 13, and you should reach a tight-ish right-hand corner. Use
Right + R to take it without losing speed, then move to the right
of the track for turn 15. This is a 90-degree left hander which has
quite a narrow circuit. Use Left + L to take it flat out, and try not
to clip the inside of the corner when going around it. Turns 16 and 17
have the anti-magnetic coating on them, so don't turn too sharply
and do not use the L or R buttons.

Turbo: Use just after turn 4 as the next few corners are open enough
to be taken at the high speed you will be doing.
