A fold suggests a seesaw's pivot; this version puts the challenge on a single tilting board.
Guide the marble toward its target by gently tilting your phone. Learn the board's response, start a run and compare local records. Three boards are free; a fourth board is part of the one-time unlock when its purchase is available.
On a non-folding iPhone, device tilt is the control. Motion input must be available. Live two-panel folded play is unavailable in this version; gameplay pauses if an unsupported folded state is reported. Do not bend an ordinary phone.
Progress and results stay on the device. There is no recording, sharing or online score service. Advertising and rewarded-video trials are disabled in this version.
