This is the eighth Chain Puzzle in the Tabletop Games series, in which all puzzles are themed around board games, card games, tile games, and the like. The answer to this puzzle is a thematic word or phrase. The solver whose answer is awarded the green checkmark has first refusal on the opportunity to create the next puzzle in the series, which must somehow incorporate the answer to this puzzle somewhere within its construction. The solver is under no obligation to create the next puzzle - in the event that the solver does not wish to take up this opportunity, the puzzle's setter may take up the offer of a willing substitute setter or choose to continue the chain themselves.
The answer to the previous puzzle (which provided the theme for this one) was TARGUI.
"Don't tell me - I can guess," I said to my friend when she opened the door to me yesterday evening. "There's a board game out on your table, which isn't the game we're going to be playing together tonight, but it's set up in some contrived puzzle-like manner to indicate the name of the game we'll actually be playing. Am I right?"
In response my friend merely laughed, let me past and gestured towards the table. Sure enough, there upon it were two partially set-up games of Targui, the second of which had also been painted in various colours:
Colourblind-friendly version of the second board available here.
Seeing the look of confusion on my face, my friend explained: "Each Targui board depicts a grid-deduction puzzle of the same variety. In order to solve the puzzle on the second board you'll first need to infer certain information from the already-solved one on the first board. As a hint, the specific grid-deduction puzzle type I've used is incredibly incongruous given the desert setting of Targui. No knowledge of the rules of Targui is required."
TASK: Identify, set up and solve the grid-deduction puzzle concealed in the second Targui board. Then derive the name of another tabletop game from the solution - this is the next game to be played.
Just for your information, the tiles occupying the cells of the second row of the first board are known as (i) Settlements, (ii) Sand Dunes, (iii) Mountains, (iv) Salt Lakes, and (v) Oases, in that order (in case you wish to use this terminology in your explanation):
(And yes, I hand-drew them all in MS Paint...)
Acknowledgement, in the name of transparency: Unlike my usual PSE puzzles, the grid-deduction components are not created entirely from scratch but are to some extent based on templates generated with the help of this website (SPOILER).
Chain Puzzles are a novel approach to puzzle series creation, in which the solver of the previous puzzle in the chain becomes the setter of the next.
