Do NOT say 21!

Do NOT say 21? More like do NOT play this.

[h1]Strategy to win bellow[/h1] A single puzzle and a little twist at the end. Takes 5 minutes to complete, and I now know a fun party trick. I bought a DLC (literally described as "donation DLC"). This made my day, good job. I like this use of AI. The game is so simple and short that I understand using AI to generate the few needed assets rather than paying someone for it. The use of AI is properly disclosed, and the DLCs are clearly flagged as "donation" material. [h3]Strategy to win[/h3] Read this if you're dumb and don't wanna bother your fat rear to try beating a basic puzzle. [spoiler]At the end of your turn, [b]you're guaranteed to end on [last number you played] + 4 in your next move[/b]. From 0, if they play 3, you can play 1. If they go 2, you go 2, and if they go 1, you go 3. Since you need them to play 21, you'll want to play [b]16[/b]. With the +4 rule, [b]if you end your turn on 16, you're guaranteed to end on 20 afterwards, from which they will be forced to play 21[/b]. Thus, you'll want to end your turn on any of the following : 4, 8, 12, 16 or 20. Once you end on any of these, you can jump to the next one using the +4 rule. Turns out [b]a good player who goes second will always win[/b]. Since you go first from 0, they can use the +4 rule to climb to 4, then up to 20. [b]The AI is purposely flawed to leave you a chance to win[/b]. It seems to play randomly until it's in range of 16, at which point it will play well (though I got one or two games where they happened to play perfectly).[/spoiler] Not a GOTY, but this game caught me off-guard and gave me an unexpected and fun experience, without trying to artificially extend its lifetime.
