The rules you’ll often see:
Number (X): Sum of pips in that region = X
Equal (=): All halves in that region must have identical pip values
Not Equal (≠): All halves must differ
Greater / Less Than: The sum must be greater or less than a threshold
Understanding those is key to solving the puzzles.
Hints & Answers for September 27, 2025
Source: JagranJosh provides a full breakdown of the clues and final placements.
Here’s how the puzzles break down:
Easy Puzzle
Hints / Clues:
Number (4): Place [1 | 6] vertically, [4 | 3] vertically
Number (6): Place [4 | 3] vertically, [2 | 2] horizontally
Equal (=1): Place [1 | 1] vertically
Solution Strategy:
Start with the “Number (4)” and “Number (6)” regions — they are more constrained because there are fewer ways to sum to those numbers with domino halves. The “Equal” region is simpler because all halves must be the same. After placing those, the rest of the dominoes will fit more naturally.
The final “Easy” solution places dominoes accordingly (as per the published solution image).
Medium Puzzle
Hints / Clues:
Greater Than (2): Place [4 | 4] vertically
Greater Than (2): Another instance — place [2 | 2] vertically
Less Than (2): Place [0 | 0] vertically
Not Equal: Place [4 | 4], [2 | 2], [0 | 0], [1 | 1] in that region
Number (7): Place [1 | 1] vertically, [3 | 3] horizontally
Solution Strategy:
Use Greater / Less constraints first — they give you bounds that limit options heavily.
Not Equal region is tricky: you must ensure all halves differ, so pick a set of distinct values.
Finally, use the “Number (7)” region to place remaining dominoes by elimination.
The published solution fits those constraints.
Hard Puzzle
Hints / Clues:
Number (1): Place [1 | 2] vertically
Number (2): Place [1 | 2] vertically
Number (3): Place [3 | 1] horizontally
Number (2): Place [2 | 2] vertically
Number (1): Place [1 | 0] vertically
Number (1): Place [3 | 1] horizontally, [1 | 0] vertically
Equal (1): Place [1 | 1] vertically, [1 | 5] vertically
Number (4): Place [4 | 4] vertically
Not Equal: Place [2 | 2] vertically, [1 | 5] vertically, [4 | 4] vertically, [3 | 3] horizontally, [1 | 6] vertically
Number (3): Place [3 | 3] horizontally
Number (4): Place [4 | 2] horizontally
Number (4): Place [4 | 3] horizontally
Number (0): Place [0 | 6] vertically, [0 | 2] horizontally
Number (18): Place [1 | 6] vertically, [0 | 6] vertically, [6 | 2] vertically
Equal (2): Place [4 | 2] horizontally, [6 | 2] vertically
Number (2): Place [0 | 2] horizontally
Equal (3): Place [4 | 3] horizontally, [5 | 3] vertically
Number (5): Place [5 | 3] vertically
These placements handle multiple overlapping constraints. As you place one domino, regions get further constrained, narrowing your choices.

Tips & Strategy: How to Use These Hints Effectively
Start with “Number” and “Greater / Less” clues — they’re more restrictive.
Then do Equal / Not Equal regions — these often force consistency or uniqueness constraints.
Use elimination — keep track of which domino tiles are left; sometimes the only way a region can be filled is by the remaining tile(s).
Avoid guessing early — try to logically deduce each placement. If stuck, backtrack a few steps.
Work region by region, but also keep an eye on global consistency (i.e. you can’t use the same domino twice).
These techniques help you solve without resorting to trial and error.
