Gate Sort: Plane Puzzle

You're the ground controller. Planes wait in lanes, the taxi loop has only a few slots, and every plane has to park at a terminal of its own color. Choose the order you send them out, and keep the loop from jamming. Gate Sort is a calm, fair sorting puzzle. NO TIMERS, NO RUSH Nothing moves until you send a plane. There are no clocks, no lives and no energy. Take as long as you like over every move. EVERY LEVEL CAN BE WON Every level is checked by a solver before it ships, so each one can be cleared without undos or hints. When the loop jams, it was the order, never bad luck. HINTS THAT SHOW YOUR MISTAKE Stuck? A hint checks whether your level can still be won. If it can't, it takes you back to the last point where it could and marks the plane that was the mistake, so you can see what went wrong. If it can, it rings a lane that keeps the level winnable, and never plays the move for you. UNDO AND RESTART Undo a move when you change your mind, and restart a level whenever you like. You start with hints and undos, and collect more from a daily reward and a reward every 10 levels. WHAT'S INSIDE • Hundreds of levels, from gentle starters to real brain-teasers • 2 to 4 lanes, colored terminals that open in turn, and lanes that stay locked until a terminal clears • Oval, figure-eight, S-bend and rounded taxi loops • A cozy toy-airport look with chunky planes in four colors, each with its own tail marking, and a backdrop that changes from one level to the next: mountains, farmland, a small town or the city • Plays offline, with no account needed Clear a level, open the next one, and see how far your planning takes you.
