Successful completion of Championship Lode Runner provided the player with a victory code, which could be written on a special card included with the game (photocopies were not accepted) and mail it in for a free certificate.
Several computer magazine staff members (such as Computer Gaming World's Roe R. Adams) contributed level designs.
A hint book was available, sold separately, but it didn't include a solution for the final level.
Lode Runner disk
You weren't allowed to play the levels in Championship Lode Runner out of order. But if you had the original Lode Runner, you could boot it up and swap in the Championship Lode Runner disk to use the free-life and level-skip features. (However, you didn't get the victory code at the end when you did it this way.)
