Checking the Dice on Jellyfish

While it is impossible to prove that Jellyfish never manipulates the dice you can at least satisfy yourself that Jellyfish has not manipulated the dice in any one particular game.

At the end of the game you wish to examine, you must notate the seed and counter, which can be found in the status bar at the bottom right of the Jellyfish window.

Once you have done so, print out the moves of the game. These are found in the file GAME.GAM, in the directory from which Jellyfish is run. Once you have accomplished this, count the total number of moves for each player, and subtract this from the count that you have noted.

Start a new game, and go to Settings >> Seed and set the seed and counter to the values they were at the start of the match you are checking.

As you continue to play you should notice that the dice that are generated are exactly the same as those from the match that you have printed.

You may repeat these steps as many times as you like, and you should see that no matter what the state of the board may be, Jellyfish always generates the same sequence from the given seed and counter.

In order to satisfy yourself that Jellyfish is not using foreknowledge of the dice it is about to generate play a game, and produce a listing of GAME.GAM.

Check Settings >> Manual Dice, so you can feed in the dice throws yourself, this way Jellyfish will have no way of knowing what dice are about to be thrown.

Continue to play the game, feeding in the dice values from the game you have listed.

You should find that it proceeds in exactly the same way as it did when Jellyfish was generating the dice.

This demonstrates that JF will play the same board, the same way, even when it is not generating the dice, and thus can have no idea what throws will be made.
