Fun
I enjoy solving chess puzzles, Go problems, and tsume-shogi; my over-the-board play is much more modest.
I also like pencil-and-paper puzzles such as Sudoku, Kakuro, Slitherlink, and Masyu.
Below is my first original Sudoku variant puzzle. I'd love to hear your feedback.
Arithmetic Thermometers (SudokuPad)
Normal sudoku rules apply.
On each thermometer, the digits from the bulb to the tip form a strictly increasing arithmetic progression. Each thermometer may have its own common difference.
If thermometers share a cell, each thermometer is read independently in its own bulb-to-tip direction.
Bonus: After solving the grid, can you find the hidden loop?
The thermometers connect tip-to-bulb to form a single 80-cell closed loop around the central cell. Along the loop, every tip, bulb, and non-thermometer cell is a turn; the loop may not pass straight through any of these cells.
Logic puzzle games are another favorite, especially those built around simple rules and surprising consequences.
Here are a few that I particularly enjoy.
I solve problems on Project Euler. My favorite problems are those where the underlying mathematical structure leads naturally to an efficient algorithm.
I play Minesweeper casually. My Expert PB is 84 seconds on a board with 3BV=175.
