If you’ve read this blog during the last few months then you probably know I like to spice up the Royal Game by mashing it up with other games such as Backgammon or Among Us. I’ve now decided to take it to the next level by combining the Royal Game with Tetris 99.

For those unfamiliar with the concept, Tetris 99 is an insanely cool game from the Battle Royale genre. The aim is to be the last one standing. Your playing arena is at the centre of screen, and you have 49 opponents on your left and another 49 on the right. Doing the math is left as an exercise for the reader. You can clear lines and send them to opponents, and they can return the favour. I thought it would be even cooler to have Spider Solitaire instead of Tetris, if only because both games have exactly 10 columns in the tableau.

If I were tasked with designing Spider 99, I would start with one-suit only, as shown in the diagram. After all the game is supposed to appeal to a large audience (presumably most of whom will be novices). Besides there won’t be much time to strategize for complex move sequences. Clear a suit and you get to damage other players by forcing them to prematurely deal a fresh row of 10 cards. You can get combos by e.g. clearing suits for two or more moves in a row. And don’t forget your opponents will be looking to do the same to you 😊 You can change your “settings” to target random opponents, opponents close to dying, or opponents who are attacking you. If you K.O. somebody then you win badges and your attacks become more powerful. If you top out by having too many cards in a single column then game over. Technically, it should be “bottom out” since unlike Tetris 99 stacks start from the top not the bottom. But you know what I mean.

Once you get down to 50 players remaining we can up the difficulty level by moving from 1-suit to 2-suit. And of course, 10 players remaining means we get the dreaded 4-suit level. And before you ask … rot13(haqb) is not allowed. The original Tetris 99 music is one of many reasons why that game is awesome and I see no reason to change it.

Unfortunately, I don’t have the smarts to program Spider 99 by myself, so this will remain as a thought experiment only. But at least I have a reason to add a new post to my blog. 😉 Of course if you have any other insanely cool ideas for mashing up anything with Spider Solitaire then please let me know. Until next time happy Spider Solitairing.
