What's New in CalcRush 1.0.2 We've completely rebuilt the onboarding experience to get you into your first battle faster, with an interactive drawing tutorial that teaches you the game mechanic hands-on before you face a real opponent. The ink system has been redesigned — you now get 5 matches to start, with 1 ink refilling every hour so you always have a reason to come back. We've also fixed a scoring exploit in Daily Challenges, improved app performance throughout, and made the battle experience smoother from start to finish. Thanks for playing — see you on the leaderboard.
