Range Call puts four targets in the sight and names one of them. Tap that mark before the clock slips. A wrong mark leaves the call where it is, and the targets change place each hit.
Clear the sight to start the set over. Four hits clear the range. Range Marks and the sight book keep the clear. The sight desk stores sound, vibration, and motion. Claim the daily sight once per local date.
Tap the called target among four live marks.
