What is the Puzzle 21 - Blackjack Solitaire Hybrid game, how does it work?

According to the introduction of Jeffrey Laird, Puzzle 21 - Blackjack Solitaire Hybrid is a Card game on the Android platform. There is currently a 0.805 version released on Mar 23, 2020, you can see the details below.

Welcome to Puzzle Twenty-one; a whole new puzzle challenge! In this original puzzle game you must get the most points from a deck of cards by making columns that add up to 21.

This is NOT a gambling game. It is a solo puzzle game inspired by crossing Solitaire and Patience with the scoring system of Blackjack.

♠️ HOW TO PLAY ♠️
Take one card at a time from the deck, and assign it to a column. Attempt to make the sum of the cards add to twentyone, but don’t go over.

Between getting a new card, you may choose to hit ‘Stay’ to take the points, or you can take a chance and draw the next card.

Aces are worth 1 or 11 points. Getting a Twenty-one is worth double points, getting a Blackjack (a Twenty-one with only 2 cards) is triple points!

The goal: Get the most points with a deck of 52 cards.

♠️ FEATURES ♠️
● Excitement: Just the right mix of skill along with the thrill of getting lucky, but without a gambling component.
