What is this game?

Shishagon is a minimalist numerical logic puzzle game. The name derives from hexagons and its unique calculation mechanics. In the game, you must distribute values between nodes to eventually reduce every node's number to exactly zero. It's custom-built for players who love mathematical reasoning, brain-burning puzzles, and a zen, stress-free environment. There is no time limit, only pure logical deduction. Solving a level can take anywhere from a minute to tens of minutes, acting as true 'gymnastics for the brain'.

How to Play

The board features circular nodes with numbers, connected by lines. The gameplay is unique: when you click and drag from one node to a connected one, the starting node's number is halved (or modified), transferring a value to the target node, based on specific level rules of addition/subtraction. The ultimate goal is to execute a series of transfers that reduces all node numbers on the board to exactly zero. If a node goes into negative or cannot be legally distributed, you must undo or restart. This requires highly precise mental math and reverse engineering of steps.

Beginner Tips

  • Understand the distribution rule: Before moving blindly, spend a minute dragging randomly to fully grasp how numbers transfer and decrease, then hit reset immediately.
  • Start with big numbers: Usually, nodes with large numbers are the 'source' of the puzzle. Figure out how to safely distribute these massive numbers first.
  • Mind the parity: Halving and transferring often involves odd and even shifts. If the rules don't allow decimals, ensure parity is correct before transferring.
  • Find isolated nodes: Edge nodes connected to only one or two others usually have a single unique solution. Solving them first locks in parts of the answer.
  • Move step-by-step: After every single move, pause to check if the other nodes can still reach zero. If a node turns negative, undo immediately.

Advanced Strategy

Reverse thinking: Since the goal is all zeros, assume all nodes are zero and deduce backwards. Ask yourself: 'What must this number have been right before it hit zero?'

Build mathematical models: For extremely complex levels, treat it like a system of linear equations. Use the connections to outline simple algebraic relationships to find the unique solution.

Reserve a 'trash can' node: Sometimes you need a central node to temporarily hold excess numbers for redistribution. Treat it as an abacus cache.

Common Mistakes

Aimless trial and error: Dragging randomly among connected nodes hoping to hit zero by luck. Luck does not work in this rigorous mathematical game.

Zeroing key nodes too early: Seeking a quick clean-up by zeroing a hub node, resulting in the nodes on either side being unable to transfer values to each other.

Fear of resetting: Making a dozen wrong moves and vainly hoping to salvage it with complex transfers. Faced with chaotic numbers, hitting reset is often most efficient.

Who is this game for?

Shishagon is the perfect game for hardcore puzzle solvers, math teachers, and adults who love numerical logic. It's not for action-seekers, but for those who enjoy contemplation and pushing their intellectual limits.

Mini Metro

Though about planning subway lines, it shares the minimalist aesthetic and heavily tests planning the flow of resources (passengers/numbers) between nodes.

Sudoku

The classic number logic game. If you enjoy filling in numbers through rigorous deduction without time pressure, the joy is mutual.

Threes!

Another phenomenal number-combining game sliding grids to add numbers. Though more of an elimination game, it equally requires strong numerical planning and foresight.
