  1. I'll start by loading the coaster tools.

  2. ToolSearch
    {"max_results":15,"query":"select:new_ride,place_piece,place_pieces,valid_next_pieces,piece_geometry,undo_piece,get_state,finish_and_test,best_result,demolish"}
    No matching deferred tools found
  3. ToolSearch
    {"max_results":20,"query":"coaster new_ride place_piece finish_and_test"}

  4. Let me plan geometry first, then build. Let me check piece geometry and start a ride.

  30. Improved to **5.34** with tripled air time, banked. Intensity is only 4.86 — lots of headroom. Let me add a second inversion (a mirrored corkscrew) for more excitement.

  37. Excitement **5.54** with 2 inversions, banked. Intensity only 4.92 — big headroom. The drop is small (highest_drop 12). Since the drop always ends at the same point regardless of lift height, I can safely make the lift much taller for a bigger drop and more speed. Let me try a taller lift.

  85. Excitement plateaued at ~6.42 (airtime saturated), though similarity improved. My best remains 6.42. Let me try one more lever — a taller first drop for more speed — building on the v11 layout.

  91. New best: excitement **6.50**, intensity 8.31, 4 inversions, highest drop 24. Let me confirm the banked best result.

  93. My best is locked in at **excitement 6.50**. I progressed from a simple 0.6 oval to a strong twister by iterating on the levers that mattered: a 200ft chain-lift first drop, a triple-sharp-60° ejector-airtime run, **four corkscrew inversions** (alternating pairs so they cancel laterally), and a fast ground-level bunny-hop return. Intensity sits at a safe 8.31 (well under the 10 cliff), nausea 4.48, and similarity is only 0.35 — original enough to avoid any penalty. **Best coaster: an original steel twister with 4 inversions, a 24-unit first drop, 97 air-time, and 13 drops — banked at excitement 6.50** (intensity 8.31, no crash).
