Tetranea vs SumLock

I built this game to combine two of my great loves in gaming: simple abstract spatial strategy, and deep, complex card deck builders. You can play it for a few minutes at a time, or really get into it and go down the rabbit hole of nearly 100 special cards with special powers. It looks kind of like one of the gazillion tetromino-placing games — pretty simple, usually full of ads, and not much more than making sure you lose after some arbitrary amount of time so they can show you more ads. This one is different. There's tetromino (and pentomino) placement to score points, but the whole game rests on your own deck of cards: shape cards you play on the board, and special cards with special powers. You play runs - series of boards that get harder and harder. Each board needs more points to beat, and some boards have bosses that do all kinds of crazy things. You can play short runs, long runs, and even infinite runs. Each run you get to add new cards to your deck and modify (or delete) existing ones. I've been working on this game for two years now, and I keep adding to it and polishing it. It's become a labor of love. I play it myself often, and friends I've introduced it to generally get hooked. The full game is free to try. There's just one single purchase that unlocks some of the run types.

Have you ever wanted a brain teaser that perfectly combines logic, math, and the pure satisfaction of cracking a safe? SumLock is the answer. Most puzzle games rely entirely on vocabulary or repetitive patterns. SumLock is different. It’s a beautifully dark, immersive numbers game where you use deduction and quick arithmetic to break open a 6-digit master code. Crack the Master Code: You have exactly 4 attempts to break the lock. Each row forces you to think strategically, shifting your digits as you hunt for the hidden combination. The Ultimate Math Challenge: There's a catch! Every single guess must consist of 6 completely unique digits, and their total sum must exactly match the Target Sum displayed at the top of your screen. It's a brilliant double-layer challenge for your mind. Color-Coded Clues: Hit "LOCK IN" to submit your combination and see how the vault reacts. Green means the digit is in the perfect spot; Blue means it's part of the code but needs to move; Red means it's not in the code at all. Build Your Winning Streak: Keep your mind sharp and see how many locks you can open in a row. Save your records automatically and push yourself to beat your personal best streak. Why SumLock?
