## What is Blitz21?

Blitz21: Fast Card Puzzle is a fast-paced card brain game that puts a strategic twist on the classic game of 21. Place cards into columns and try to reach exactly 21 in each one. Go over and you bust, but hit 21 perfectly for massive bonus points.

HOW TO PLAY
Cards are dealt one at a time from the deck. Place each card into one of four columns. Your goal is to make each column add up to exactly 21 for maximum points. Getting close to 21 still earns points, but going over 21 busts that column. Clear all four columns at 21 for a Blitz bonus multiplier.
