    I'm organizing a vibe coding game dev competition▲7

    Hi everyone, I just saw a vibe coded game on HN, and thought maybe I should post about this here. I'm organizing a vibe coding game dev competition called Vibe Jam. Last year we did it too and there was 1000+ games submitted. This year the deadline is May 1 and you can submit your games until then. There's $35,000 in prizes with the Gold prize being $20,000. Let me know what you think! -Pieter

    I made a game for a non-gaming tech company▲7

    I got the chance to create a whimsical game about their latest Adaptive Pricing feature, despite Stripe being a very serious financial company. I'm in an interesting place being able to be paid to make games for a non-gaming tech company.

    I built a social experiment to test your curiosity▲6

    I had an idea for this concept for a while and decided to build a little website around it. It's kind of a silly idea but I'm really curious to see how it plays out. If you're a particularly curious person, be warned. By submitting a payment to the game, you get to see how many other people were curious enough to play. You will be ranked based on your payment amount, and get to discover some interesting insights about the game's dynamics. Hope you like it

    Never let friends forget who is the winner▲5

    Hi HN, I made a simple little app to keep track of game rankings with friends. It uses the Elo system (like in chess) to adjust scores after each game. Works for board games, chess, padel, tennis, or anything that’s competitive. It’s free — give it a try
