Answers to common questions about Mehen for iPhone and iPad, plus a way to reach a human when the answer isn't here.
Questions, bug reports and suggestions are all welcome — send an email and describe what happened.
nsat-dev@pm.meThe full rules are always available inside the app — tap Rules on the title screen or from the top bar during a game.
Each turn has three moments. One player secretly hides between one and five marbles in a closed fist. The other player guesses how many.
Pieces travel along the coiled serpent from the tail toward Ra at the center. Land on a rival's piece and the two swap places; land on your own and yours leaps ahead.
Bring every one of your pieces all the way along the snake and into Ra at the center. You don't need an exact count to finish — any move that would carry a piece past the final square sends it home to the sun.
When you guess correctly you may unleash a lion onto one of your opponent's pieces instead of moving your own. That piece is pinned and cannot advance until its owner frees it. Lions make a strong position suddenly fragile, so they're often worth more than a few squares of progress.
Not in this version. Mehen is currently single-player: you play as red against the computer, which plays blue. Three opponent strengths are available in Settings — easy, medium and hard — and each one bluffs and guesses differently.
Open Options from the top bar. You can set the opponent's strength, choose one to three pieces per player, and switch haptics or the move log on and off.
Because difficulty and piece count change how a game is set up, confirming with Apply & New Game starts a fresh game. Finish your current game first if you want to keep it.
Mehen saves your game automatically, but a save is kept for seven days. After that it expires and the title screen offers only a new game.
A save is also replaced when you start a new game, or when you confirm changes with Apply & New Game. Only one game is saved at a time.
That's intended. On iPhone the board is designed for portrait and stays there, so the spiral is never cropped. On iPad the game rotates freely and supports all four orientations.
Mehen uses short system tones rather than a music score, so it's quiet by design. If you're hearing nothing at all:
First check that Haptics is switched on in the app's Options. If it is:
Work through these in order — most problems clear at the first or second step.

Mehen collects nothing. There is no account to create, no analytics, no advertising, and no network connection of any kind. The full policy is published at nsat-dev.github.io/policy.html.
Mehen uses a dark, high-contrast palette throughout, with large tap targets on the board and marble controls. Haptic feedback can be turned off entirely in Options if you find it distracting, and the game never relies on sound to convey what happened — every result is shown on screen and recorded in the move log.
If something about the game is hard to see, hear or reach, please write in and say so. It genuinely helps.
The more of this you can include, the faster it can be fixed. Rough notes are fine — send what you have.
