Location: India | Hashi -1 : Use the "No islands" rule throughout the grid - inspired by a comment from Prasanna that very few Hashi puzzles use this rule extensively
Hashi -2 : Masyu like chain which goes from top left to bottom right
Hashi -3 : Interaction of two 5's near the center
Hashi -4 : Interaction of the 4 and the 5's at the center. This one was my personal favorite for the entire set
Magnets 1 : Easy puzzle used to replace a harder magnets puzzle
Magnets 2 : Existence of half the grid size (8/2 =4) in one of the polarities forces a few bars to be magnets
Magnets 3 : Min max - A less loaded column surrounded by two heavily loaded columns.
Magnets 4 : Transfer of polarities across rows
Arrows 3: 3 in the center gives good starting point
Arrows 4: Interaction of two large numbers in the corners (4 and 5) along with the smaller numbers int he remaining two corners (2 and 3)
Anglers 2: Parity - Only one angler can reach the fish on bottom left as it has different parity compared to all other fish
Anglers 4: Reach ability of top left fish to an angler
Multi-anglers- Count of total number of anglers and how many anglers can reach each fish. |
