ALPHASTACK vs Pocket Screw Machine

ALPHASTACK is a simple physics game where you stack letters from A to Z, in order. The controls are simple. Tap where you want, and the letter drops straight down. No left-right adjustments. No skills required. But the moment a letter falls below the base, it’s game over. It’s okay if the stack collapses. It’s okay if it overlaps or tilts. As long as it doesn’t fall, you continue. If it falls, it ends. Physics behavior changes every time. Collision detection faithful to the actual shape of each letter. Difficulty is always the same — only luck and intuition matter. Instant restart after failure. Stack from A to Z to clear. Nothing more. Nothing less. Short sessions. Before you know it, you’re playing again. A game that’s meaningless — yet impossible to stop.

Pocket Screw Machine is a color-sorting screw puzzle with a moving twist. Instead of stacking screws onto a bolt, you spill screws onto a spinning machine and let timing do the sorting. Tap a panel drop its screws onto the rail, and watch each color thread itself into its matching plate as the ring carries it around. Fill every plate to win. Overload the rail and the whole machine seizes up. HOW THE MACHINE WORKS • Tap a panel to loosen its screws onto the spinning rail • Four color plates sit around the ring — each one takes three screws of its color • As the machine turns, every screw passing its matching plate drives itself in • Fill a plate and it locks shut; the next color rolls up behind it • Clear all the plates to finish the level KEEP IT TURNING • The rail only holds so many screws, release colors with nowhere to go and it jams solid • Read the machine before you tap: open the panels whose colors have an open plate • No move counter, no timer, you only lose if the rail jams for good • Every level is a small sorting puzzle built to be untangled PARTS THAT CHANGE THE GAME • Mystery plates: The next color stays hidden behind a "?" until it rolls into place • Gates: Run a screw through and it splits into more • Tunnels: Feed a whole extra run of panels onto the board • Arrows: Panels that you can only unlock from a certain direction WHY IT'S HARD TO PUT DOWN • A fresh, tactile spin on the nuts and bolts puzzles you already love • One-tap, simple, with real timing and planning underneath • Hand-built levels that stay clever without ever feeling like work • Oddly satisfying to watch, screws driving home, plates locking in sequence • Play offline, anywhere, no wifi needed • Free to play, with lives that refill over time Loosen the screws. Run the machine. Sort every color.
