About

Project Rail

Features
Read full description

RAIL is a calm strategy arcade game built on one rule: you never control the trains, you control the world. Swipe any row or column and the whole lane slides one step, tracks, trains and all. The board wraps around, so nothing ever leaves. Trains keep rolling while the landscape shifts beneath them. Guide every pastel train to the station of its own color. A broken connection does not end the game right away. The train pauses, glows amber, and gives you one breath to rescue it with a clever shift. Land five deliveries in a row and you enter Flow, where every arrival counts double. FEATURES - One gesture, endless depth: swipe to shift rows and columns - Every run is a new board with fresh stations and tunnels - Incoming trains are announced ahead of time, so you plan instead of panic - Wordless first ride that teaches the game in seconds - Minimal design, soft pastel colors, subtle haptics - No account, no ads, no internet needed Short runs, deep planning, zero stress. How long can you keep the world moving?

Every igloo needs one penguin beside it. Can you find where they all belong? Huddle is a cozy penguin logic puzzle and relaxing brain teaser set on a drifting Arctic ice floe. Study the number clues, place exactly one penguin next to every igloo, and make sure no two penguins sit side by side. The numbers around the board show how many penguins belong in each row and column. Every hand-checked grid has one logical solution. No guessing. No timers. Just calm, satisfying deduction. EASY TO LEARN. DEEP TO MASTER. • Place exactly one penguin beside each igloo. • Match the penguin totals for every row and column. • Keep penguins from sitting next to one another. • Use Snow Notes to mark cells that cannot hold a penguin. Begin with gentle floes that teach the rules naturally, then work your way up to larger expert puzzles. A friendly scout helps you get started, while Auto-Snow clears obvious cells so you can focus on the clever deductions. A FRESH PUZZLE EVERY DAY Daily Drift brings a new hand-checked brain teaser each morning. Monday’s Expedition delivers one giant ice floe to solve throughout the week. Build your streak—and mend it if a day melts away. EARN EVERY SNOWFLAKE Solve efficiently to beat par and earn three snowflakes. Keep every heart for a flawless victory. One smart penguin placement can reveal an entire drift of snowy cells at once. BUILD YOUR HUDDLE Earn coins as you play and unlock a charming collection of penguin friends. Solve beneath bright daylight, warm golden hour, or the glowing northern lights as Huddle’s Arctic world changes around you.
