Why waste plastic on dice when you can click, "new roll" on your phone? Some people might like games like this because they're not digital.

Not everyone has an iPhone. Young children do/should not have smartphones. Paper does not require constant updates, maintenance and bugfixes. Paper is cheaper. People want to play physical games without the distraction of devices. People don't want the hassle of downloading an app before they can play a game. If the complexity of scoring requires an app, it's too complicated.

I think there's scope for including the scoring as part of the packaging, no "waste paper". My first inclination is a two part sleeve - but I'm assuming then it's a two player game, more players requires some ingenuity - the sleeves start at zero score and cover the lower numbers, moving towards the highest possible score at the centre as the sleeves meet and cover the whole container.

Perhaps a graduated stick, like a long cocktail stick/drink stirrer, for each player, you pull the stick across a line (eg from under the box) to indicate the score. Another way would be to have a stack of counters, like tiddlywinks, you could upsell different counter sets then (half marbles, cut stones, metal, different designs). Counters might work for tie-ins - planets of the Starfleet federation, planets named for houses of GoT or such. Or yes d10's as a sibling comment mentions.

Doesn't mean you couldn't have an app too, but then why not simulate the dice, etc., if you're going to need an app to play the game?
