Collect 1,000,000,000 studs (Single Player)
Collect a billion studs across your save - the big grind. Buy and enable every stud-multiplier red brick (the x2/x4/x6/x8/x10 bricks stack up to x3840), then farm studs in a stud-rich level or the hub. With the multipliers on, a billion comes surprisingly fast.
