Theme: Utopic

Author/Opus: This is the 205th puzzle from our contributing puzzlemaster Serkan Yürekli.

Rules: Variation of Statue Park and loop puzzle rules (using a standard pentomino set).

Place each of the twelve pentominoes into the grid once, with rotations and reflections allowed. No two pentominoes can overlap or be orthogonally adjacent, and all cells not occupied by the pentominoes must be traversed by a single, closed loop (connecting cells horizontally or vertically). The black circles indicate some cells that must be covered by pentominoes, white circles indicate spaces that may not be contained in pentominoes and must be part of the loop.

Time Standards (highlight to view): Grandmaster = 7:30, Master = 11:30, Expert = 23:00

Formed Cave by Serkan Yürekli

Cave by Serkan Yürekli

PDF

Theme: Clue Symmetry and Logic

Author/Opus: This is the 198th puzzle from our contributing puzzlemaster Serkan Yürekli.

Rules: Standard Cave rules; also, all groups of cells outside the Cave must be formed out of different arrangements of exactly five cells (i.e., different pentominoes). Pentomino shapes may be reflected or rotated, but they cannot repeat or touch each other. Not all pentominoes need to appear.

This example uses four cell regions (i.e., tetrominoes) within the same rules.
