System Logic

How to play

1. 1

   Find the useful references

   Each game randomly selects one of four settings: rescue station, cargo terminal, research laboratory or rail control centre. Each has 15 references, its own rules and question types, and randomised values. Open up to two references at a time; opening a third closes the oldest.

2. 2

   Connect facts

   Use the current handbook to solve capacity, scheduling, priority, mixture, check-digit and system-rule questions. Beginner uses one or two references per question, Intermediate uses two or three, and Advanced uses three or four. Only two references can stay open, so retain facts while switching tabs. Use only stated conditions; do not add real-world assumptions.

3. 3

   Choose, skip and revisit

   Select an answer once for each of 30 questions. Previous/Next and the numbered navigator let you skip and return. Answered questions show their explanation and cannot be scored again.
