Single-player blackjack game with optional basic strategy hints.
I started on the project in februrary 2020 to get 100% offline working crosstplaform apps running on a Ubuntu Touch / UBPorts phone and as a result uploaded the app to OpenStore.

Project description

NOTICE: Absolutely zero real money involved and no in-app-purchases or alike!
You always play with virtual coins, restart the game to get the initial amount of coins again.
The coin highscore is saved, you can view it in the left sidebar.


  • To keep the game simple, the initial bet is always one coin
  • 6 Decks, shuffled after 75% have been played
  • Blackjack pays 2-to-1
  • Dealer stands on any 17 (S17)
  • Double down on any two cards (D2)
  • Double down after splitting (DAS) (except Aces)
  • No resplitting (NR)
  • No insurance (NI)

The basic strategy suggestions are based on this ruleset.

The app itself is MIT licensed, it’s a fork of kevinleedrum. My fork for Ubuntu touch has been changed to improve usability for mobile usage.

Goal of the Ubuntu Touch blog post series

This is a post about apps and games in the series of Ubuntu Touch blog posts. I got a Nexus 5 smartphone around and want to contribute to the Ubuntu Touch / UBPorts project which goals are a community-first linux mobile operating system.

Currently I’m looking for existing open source projects of all kinds and try to make them run on Ubuntu Touch. So there is something available for everyone :) As with other failed projects, if there are no apps in stores there are no users… and if there are no users no dev is willing to put time into the platform :D. My aim is to get stuff into store that works for everybody and offline.
– Quote from UBPorts community chat about the intention

Another goal is that projects are as non Ubuntu Touch specific as possible. The idea is to support other upcoming mobile operating systems & software projects like Plasma Mobile in the future.
