Switch rings only at open crossings on a rotating spiral in an endless reflex run.
The dynamic viewport prevents the browser toolbar from hiding the lowest touch target. The spiral simulation begins on load and produces new decisions continuously without a start screen. Use Left and Right when spiral requires a destination, or Space, Enter, and Action for its central timing choice. Its readable vocabulary is inner rings, outer rings, open crossings, angular speed, closed walls, completed turns, and each item participates in the rule instead of decorating a generic runner.
The visible guide marks explain open crossings so input is based on evidence rather than guessing. Ratings measure sustained command of completed turns, not idle survival or rapid random taps. Debug mode reacts to generated closed walls and therefore exercises real movement, scoring, collision, and recovery. Risk rises when closed walls appear close together, so the streak reflects genuine control.
Reset creates a clean course at normal speed and keeps the locally stored best score. After an error, rebuild accuracy with one conservative decision before attempting another narrow window. render_game_to_text exposes spiral, player position, target state, score, streak, best, speed, and autoplay for runtime checks. Read two upcoming inner rings events and decide where the player must be before acting.
Mobile portrait and landscape keep the entire spiral course visible above three forty-four-pixel controls. Speed Spiral is an endless one-input reaction game where you switch rings only at open crossings on a rotating spiral. A successful switch rings only at open crossings on a rotating spiral decision accelerates the next approach, while a miss restores a manageable pace. Practice the relationship between inner rings and outer rings before chasing a long streak.
A collision subtracts a small amount, clears the streak, and resumes safely instead of opening a terminal overlay. Correct handling of angular speed earns a base award and an increasing precision bonus. At higher speed, watch open crossings and the player glow together rather than staring at one contact point.
