Rainy tracks have varying water depths, and your lane choice directly impacts the risk of hydroplaning. Rainline Planner provides a real-time water depth map (dark blue = deep water area). You need to plan a route to avoid deep water areas while maintaining a reasonable speed. The track is open-air and has no drainage system.
Gameplay: Water accumulation significantly increases resistance and reduces grip, but sometimes there are drier lines outside the deep water areas. You need to weigh the detour distance against the loss of grip in wet conditions.
Skill Pack Details:
Water Depth Radar (Predicts water depth up to 20 meters ahead)
Drainage Path (Displays water flow direction, helping to determine the shallowest point of the water)
Water Skip Warning (Issues a warning when speed and water depth reach critical values)
Level Introduction:
Levels 100-300: Uniform water depth.
Levels 301-750: Localized puddles, detours required.
Levels 751-1450: Dynamic rainfall, water depth changes in real time.
Levels 1451-2500: Nighttime rain battle, water depth map display area halved.
Levels 2501-3900: Frequent alternation between flooded and dry areas.
Levels 3901-5900: Water depth data delayed by 5 seconds, must be memorized.
Levels 5901-8000: No water depth display, depth judged only by splashing sound.
