Nanobot Loop

NANOBOT LOOP is a conveyor belt, a row of lettered blocks, and a word they are supposed to spell. You never pick a block up. You press PUSH or POP, a courier walks over, and it carries whichever block the rules allow. A pile hands back whatever went in last. Between that and a belt that keeps cycling is the entire puzzle.

HOW IT PLAYS The top row is the name to spell. The belt below it holds the blocks, out of order. Press PUSH and the courier takes the block at the dock and stacks it on a pile. Press POP and the pile gives one back — always the one that went in most recently, never the one you wish it would. Get the belt reading the word and the track is sorted.

A PILE REVERSES WHAT YOU GIVE IT That is the whole trick, and it takes about thirty seconds to understand and a lot longer to get good at. Loading three blocks in and taking them straight back out gives you those three in reverse. Knowing when you want that, and when you have to avoid it, is the skill the game is actually about.

288 LEVELS, EIGHT CHAPTERS Each chapter changes exactly one thing, on a board simple enough that the new thing is the only hard part on screen.

SPOOL — the belt comes round. REWIND — five on the loop. PINCH — the pile holds two. SPLIT — two piles. Pick one. SEEK — one pile. Six blocks. LONGHAUL — seven, and some room. CHOKE — seven, and none. OVERFLOW — eight wide. Two slots.

THREE STARS MEANS OPTIMAL Every level ships with a par, and that par is not a designer's guess — it is the fewest presses that exist for that board, proven before the level is allowed to ship. Match it for three stars. Nothing else is being measured: not speed, not streaks, not how many times you tried.

CHANGE YOUR MIND FOR FREE Queue a few presses and watch the courier work through them. Undo takes back the plan first, and only then the moves themselves, so thinking out loud costs you nothing. There is no timer, no lives, and no way to lose a board.

CALM BY DESIGN No timer. No lives. No streak to protect. No falling anything. Nothing on this board is in a hurry, and neither are you. Built for short sessions: the train, the line, one more track before bed.

EVERY BOARD IS SOLVABLE Level 214 is the same board for everyone, forever, and every one of them has been verified before shipping. Pick up right where you left off.
