AI is totally, unfairly and consistently biased towards the computer.

probs the 2nd or 3rd best BG app after XG gammon. not a great UI, not nice colors offered. XG has better interface and engine. worse, is this app just gets ridiculous rolls all the time. when you play it all day every day.... you notice. no matter what the developer says about rolls. try it and you see and you'll be frustrated just like all of us. can't wait for XG to come back, which it is.

Excellent game, no ads, play against computer or a friend. Hints, statistics, undo. We're in the UK and the rules vary very slightly from yours.

The dices are cheating!!!! Sometimes during a game the hint gives the obviously right move, and the analyzer later judge it as a fault! I said it wrong about cheating. I only wanted to say, that the hinted action is sometimes later analysed as wrong move.

El joc de BG amb millor disseny però massa car (tot i així l'he pagat). L'oponent moltes vegades treu el llançament exacte per guanyar, més enllà de la lògica i l'estadística. Gràcies per respondre, de totes maneres. Best BG designed app but very expensive (I paid for it anyway). Many times oponent gets the exact dice rolls to win, far beyond logic and statistics. Thanks for replying, anyway

Die App würfelt nicht das, was sie braucht, sondern umgekehrt: das neuronale Netz ist gefittet auf den Mersenne-Twister mit fester Seed und pseudo-zufälliger Verteilung. Funktionsvorschlag: dynamische Seed - bei jedem Wurf die Seed mit der Systemzeit füttern. Und dann schauen, ob der Experten-Modus immer noch überlegen ist.

A suspiciously good player. Always gets the dice needed to land on you or get out of a spot. Not much fun playing when the dice are consistently in the other player's favour. Game interaction could be better too.

great game, currently playing easy and medium and winning a good percentage but with a relatively high ER.The AI seems to roll a high amount of fortunate doubles when needed and limits my die numbers when l am heading for home. Still better than other games l have tried.
