All exercises / games involve a matrix of orienteering controls in the sizes 4x4, 5x5 or 6x6. They should be far enough apart so that multiple players can be participating with their own maps.
Note that the purchase of the games is locked until the purchaser has signed a contractual promise to not share any games with other organizations. Because the games are just PDF files it would be easy to pass them on to others, so the author "protects" against this by having the purchaser sign what is effectively an NDA. It probably wouldn't hold water in court, but enforces a moral restriction.

The first image is an indication of the control numbers that should be placed. The second image (map 4.14) is a easy exercise (as denoted by the 2 stars) within a 6x6 grid. Exercise 4.53 is much tougher. Page 4.97 are the valid control numbers that should have been punched.
Some key points in random order
- In addition to the games on the USB stick, more are added constantly on a google drive accessible to all purchasers.
- A set of exercise maps need to be printed for the day's use. They can be laminated for easier reuse.
- The usb stick includes downloadable XML files so that results can be verified via software. For this feature a SPORTident timing set needed. Software such as o-store's O-Fun will do the verification and show success or to try again.
