I'll plan carefully: - Station at (50,42) heading +x - Chain lift up 5 tiles (z+96) - Banked left turn, big drop - Vertical loop (entered from a small ramp at z=120, exited back to z=112) - S-bend, camelback hill, banked turns - Return to station Let me place all pieces:

    Score improved to 5.86. Let me try to push it above 6.0 by adding a corkscrew. I'll demolish and rebuild with an improved layout.

    The roller coaster is now complete and the circuit is closed. Here's a summary of the final design: **Ride Layout (50 pieces, Twister Roller Coaster):** 1. **Station** (4 pieces) - flat station at ground level 2. **Chain lift hill** (7 pieces) - climbs 96 units up to z=208 3. **Flat + left quarter turn** - transitions to heading south 4. **Big drop** (7 pieces) - drops 96 units back to ground level 5. **Booster** (speed 30) - boosts speed for the inversion 6. **Vertical loop** - 1 inversion, entered from a small ramp 7. **Left quarter turn** - redirects west 8. **S-bend left + S-bend right** - adds lateral excitement 9. **Small hill** (up 25 / down 25) - adds airtime 10. **Left quarter turn** - redirects south 11. **Return straight with hill** - another small hill for airtime 12. **Final left quarter turn** - connects back to station **Results:** - Circuit: **CLOSED** ✓ - Inversions: 1 (vertical loop) - Drops: 3 - No crashes - Lateral G: 1.80 (within 3.0 limit) ✓ - Intensity: 4.60 (under 10) ✓ - Track bounds within limits ✓
