Collapsi Part 2 - itch Apps

After trying Collapsi a few times and describing it last month, I ended up on itch.io and found a variety of "Play in Browser" versions of this little card game.  It's a surprisingly varied selection built in different tools with a range of design approaches.

You can find them all with a quick search, and I'm sure more will be appearing.  Here are the ones I looked at:

Collapsi by Wikiti. Last update 18 Aug 2025.
This was written using the Godot Engine, and covers the basics.  Play vs Player or Computer.  When its your turn, all cards you can land on are shown in red, which is a good visual aid.


Collapsi by Mad Moon Interactive. Last update 13 Apr 2026
This one was made in Unity with a neat 3-d board layout floating far above the Earth.  Here, you click one card at a time to get where you want to go.  PVP only.


CollapsiJS by Sentinel65. Last update 22 Jul 2025.
Made in Javascript.  This was has a dropdown to choose player color, PVP, Play vs Computer, and even has 3x3 and 4x4 solo modes.  I thought I saw a discussion on this page with the original Collapsi creator (Mark S Bell) about rules details, but now I don't see it.  I like that this one has detailed analytics and statistics.

Another one made in Godot.  Everything in this one is so ... flippy.  Each letter of the main menu is a card that flip-flops.  The main game is okay, more flippy things.  Its handling of the rules and events felt right.

The point here is not who's right, or which approach is the best, but how an enjoyable new card game got out into the world and inspired many others to pitch in and code their own versions of it.

Escape from the Aquarium

Image
We found Escape from the Aquarium on the way home from our Sedona trip.   It looked cute and we didn't notice at the time that it was an escape room game for kids.   Or main issue with escape room games is that the pieces get marked up or ruined during the course of the game,  so it's hard to play them a second time.   And knowing the outcome spoils the replayability.  Escape room games are not really games, they are sets of puzzles. The art is bright and friendly.  The story is a bit silly: you get turned into a fish while visiting the aquarium and have to swim around looking for clues to get magical ingredients to get back to human form.   Okay. There is an answer book and hint book, both of them with scratch off spaces, so there's the main component that can't be restored to its unplayed state.  There are four folders full of clues but you have to dump all four folders together, since the stuff you need to solve puzzles in o...

Idle Planet Miner: Selling Your Galaxy

Image
Back in Idle Planet Miner, production was starting to bog down, with crafts taking an hour apiece, and sometimes needing hundreds of items to unlock new research.  So, I figured it would be a good time to test out their "Sell Your Planet" feature, which has so many people online asking questions. These idle games can't level up through an infinite many items, so they all have this same kind of game reset mechanism.  In Idle Planet Miner, the Sell Galaxy button shows you the value of your galaxy and how many credits you will get for it.  These credits are a kind of meta currency, letting you buy new rooms for your ships, with each new room offering a different game boost.  Clicking the Sell button will show you exactly what you will lose: all planets, cash, ores, alloys, items, research.  Which sounds terrible.  But you get to keep your dark matter, your managers, your beacon buffs (though you will have to research the Beacon again to get it back on screen),...

WarZone Idle

Image
Playing with WarZone a bit this week, I discovered that there is an "Idle" campaign at the bottom of the main page.  Either that's new, or I just didn't see a year ago when I first wrote about this great app. The Idle campaign is set up in a very interesting way.  The maps appear to be the same sequence as in the main game: you start with the standard Risk world map.  But now, you have a certain amount of money and armies shown at the top right as W and A values.  You gain some amount of each per second, and each space has an army value shown on it.  So maybe Brazil starts at 96.  Click it when you have 96 armies and it's your without a fight. Some spaces have "resources", which include Army Bases (where you can buy armies for W's), Caches (some amount of Ws and As), Mines, Forges and Crafters.  Some of these can be upgraded by spending Ws to get more per second.  You can forge ores into ingots like so many other games and sell all the resources f...
