In another Grouping: Matching Logic Game I’d written – that one was a difficult type of Matching game because the number of “prayer-answerings” per deity was not fully determined.
In other Grouping: Matching games (such as the one I’ve written below), the number of slots is fully determined for you. In these types of games, drawing multiple templates, possibilities, or limited options is often incredibly useful.
What are templates, possibilities, and limited options? They’re all different terms describing the same technique – drawing a few main diagrams instead of only one. Each main diagram you draw will represent a different potential placement of the variables.
The key to drawing templates is to identify a variable or rule that has only a few different possibilities. Once you’ve found that variable or rule, draw multiple diagrams based upon every different major possibility for it, and fill in the other variables around it.
Please post your thoughts and questions in the comments!

Here’s the Logic Game:
Compu-Global-Hyper-Mega-Net presents seven projects to the military over the course of three months- two in April, three in May, and two in June. Two of the projects are classified. Two others are electronics-active camouflage and a ballistics computer. The remaining three are weapons-a drone, a laser cannon, and a ray gun. The projects are presented in accordance with the following conditions:
The drone is not presented in June.
The classified projects are not both presented in the same month.
At least one of the weapons is presented in the same month as one of the electronics projects.
At least two of the weapons are presented in the same month as each other.
1. If the laser cannon is the only weapon presented in June, which one of the following must be true?
(A) A classified project, an electronics project, and a weapons project are presented in May.
(B) The ballistics computer is presented in May.
(C) A classified project is presented in May.
(D) An electronics project is presented in May.
(E) The ray gun is presented in May.
2. If two weapons are presented in April, which one of the following CANNOT be true?
(A) The drone is presented in April.
(B) The active camouflage is presented in May.
(C) A classified project is presented in May.
(D) The ballistics computer is presented in June.
(E) The laser cannon is presented in June.
3. If the electronics projects are not presented in consecutive months, which one of the following must be true?
(A) A weapon is presented in April.
(B) The laser cannon is presented in May.
(C) A classified project is presented in June.
(D) A weapon is presented in June.
(E) The classified projects are presented in consecutive months.
4. Which one of the following CANNOT be true?
(A) Both electronics projects are presented in the same month.
(B) Two weapons are presented in the same month as a classified project.
(C) Two weapons are presented in the same month as an electronics project.
(D) The active camouflage and the drone are presented in April.
(E) Two weapons are presented in June.
5. If neither of the electronics projects is presented in June, which one of the following must be true?
(A) A classified project is presented in May.
(B) The drone is presented in May.
(C) The ray gun is presented in May.
(D) A classified project is presented in June.
(E) Exactly one weapon is presented in June.
