Feedback from people who were tired of rolling forever
“Great Risk dice roller! I like that the history is shown all the way through attacks and defense. Really helps when dealing with multiple mass armies mid to late game and you don’t want to roll so many times. Also nice that it keeps track of losses.”
“Amazing and very useful when playing on the board. Large attacks used to take forever — now one tap and we have the result. Exactly what we needed at the table.”
“Simple and does exactly what it should. Enter the numbers, simulate all, get remaining armies. Saves a ton of time in late-game Risk.”
“We used to argue about who should roll or spend 20 minutes on one attack. This app ended that. Round-by-round history is clear and the win chance is a nice bonus.”
“Exactly what a Risk table needs. Full simulation for big battles, step-by-step when you want the drama. Clean and fast.”
“Simple interface, does the job. Win chance calculation and fight summary make it more than just a dice roller. Recommended for any serious Risk group.”
