This Friday presents three Pips puzzles. While the Easy and Medium tiers are generally manageable, the Hard Pips puzzle poses a greater challenge.
In Pips, players are given a grid of multicolored boxes and a specific set of dominoes. Each colored area defines a unique condition that must be satisfied. To win, every domino must be used to fill the grid, and all conditions must be met. The puzzles are categorized into Easy, Medium, and Difficult tiers.
A Pips grid typically features various symbols and numbers within its colored sections. For example, three purple squares might require their pips to be unequal (indicated by a crossed-out equal sign), while two adjacent pink squares could need to sum to zero. Alternatively, a series of zig-zagging blue squares might all require equal pip values. Dominoes can be rotated to fit into the grid. Additional conditions may include “less than” or “greater than” symbols, dictating that the total of pips in specific tiles must meet a numerical comparison. Blank spaces within the grid can accommodate any pip value.
The various conditions include requiring all pips within a group to be equal (=) or unequal (≠). Some tiles or groups of tiles might need to be greater than (>) or less than (<) a specified number, or equal an exact number, such as 6. Tiles without any indicated condition can be filled with any value.
Success in Pips hinges on using all dominoes to fill every square while meticulously fulfilling each condition. Some puzzles have a single unique solution, whereas others may offer multiple valid arrangements.
Solutions for the Easy and Medium Pips tiers are available, followed by a comprehensive walkthrough for the Hard puzzle.
For today's Hard Pips puzzle, it is established that the central Orange = group consists entirely of 1s. The subsequent strategy involves determining how elements from the grid's perimeter can integrate with this central group, beginning with a pair of doubles in the bottom right.
The first step involves placing the 6/6 domino from Purple 6 into Pink 9, followed by the 3/3 domino directly below it from Green 6 into Pink 9. Subsequently, the 3/1 domino from Green 6 is placed into Orange =, and the 4/5 domino above it, from Green 4, is positioned into Dark Blue 10.
Next, the 5/3 domino from Purple 10 is placed into Pink 5 in the top left corner. The 5/6 domino from Purple 10 is then extended down into Blue 12. Following this, the 2/1 domino is placed adjacent, from Pink 5 down into Orange =, and the 5/1 domino is positioned from Dark Blue 10 down into Orange =.
Finally, the 4/4 domino is placed in the left two tiles of Dark Blue =, with the 1/1 domino directly above it in Orange =. The 4/6 domino is then moved from Dark Blue = into Blue 12, and the 0/1 domino fills the last remaining Orange = tile, originating from Blue 12.
