Humble just launched the Programming Puzzles Bundle: seven Steam games where you solve puzzles by writing code, wiring circuits or building logic, starting at $6. It runs until midnight ET on the night of Monday, October 19, and part of every purchase goes to the Electronic Frontier Foundation.
The headliners are Replicube, while True: learn() and Retro Gadgets, and every game in the bundle is rated Very Positive or better on Steam.
$6 to start · everything for $14 · ends Mon, Oct 19 at midnight ET · supports the Electronic Frontier Foundation
What’s in the Bundle
Tiers stack: paying for a higher tier gets you everything below it too. All seven games come as Steam keys.
- $6: Replicube, while True: learn(), SOLAS 128
- $8 adds: Linkito, The Signal State
- $10 adds: Quantum Odyssey
- $14 adds: Retro Gadgets
Standouts
Standouts: Replicube (Overwhelmingly Positive on Steam), a puzzle game from Walaber where you write short programs that build 3D voxel shapes. while True: learn() (Very Positive from more than 8,000 Steam reviews) teaches machine-learning ideas through visual node puzzles. Retro Gadgets (Very Positive) is a sandbox for building and coding your own handheld gadgets, and it only unlocks at the $14 tier. SOLAS 128 (Very Positive) rounds out the $6 tier with light-routing puzzles.
Gary’s Call
Gary’s call: this one is for Zachtronics fans, coders and anyone who likes puzzles that feel like real engineering. The $6 tier is already a strong deal with Replicube and while True: learn(). Go to $14 if you want Retro Gadgets: it’s the deepest toy in the box and only $4 more than the $10 tier. If you just want a casual puzzle fix, skip it; these games expect you to think like a programmer.
