## What is Dyno 21?

Dyno 21 is a fast-paced card strategy game where smart decisions build streaks and high scores.
Draw or Hold to shape your hand and get as close to 21 as possible without going over the limit. Wins build your streak and boost your multiplier, turning every decision into a risk-reward challenge.
Modes:
• Run (3 Lives) — make mistakes, reset your streak, and push for a new high score
• Timed Run (3:00) — race the clock and score as high as you can
No betting. No currency. Just skill, momentum, and one-more-run energy.
What’s New (v1.0)
Initial release: two score-based modes, streak multipliers, and saved high scores.
