Mochi Beam
A smiley mochi lamp fires one glowing beam across a candy grid, and you flip and slide diagonal mirrors to bounce it through every crystal at once.
About Mochi Beam
Mochi Beam is a single-beam reflection puzzle. A cute mochi lamp sits on the edge of the board and fires one glowing beam straight inward. That beam keeps going in a perfectly straight line until it meets a diagonal mirror, hits a sleepy cushion, or runs off the grid - and your job is to steer it so it passes through every sparkling crystal on the board. The moment a crystal sits on the beam's path it lights up, and lighting all of them at once clears the level.
You steer with the mirrors. Each ordinary mirror is a diagonal bar that points one of two ways - a forward slash or a back slash - and tapping it flips between the two, instantly re-routing the beam so you can watch it swing to its new heading. Because the beam is always shown live, Beam is less about hidden math and more about reading the bounce: nudge one mirror, see where the light lands, then nudge the next.
The 20 hand-tuned levels are grouped into five candy worlds - Berry, Citrus, Mint, Ocean, and Galaxy - and each world layers in a new piece. Mint adds sleepy cushions that stop the beam dead so you must route around them. Ocean bolts some mirrors at a fixed angle (you can't flip those) and introduces rail mirrors that you drag along a track instead of rotating. Galaxy brings portal pairs, where the beam dives into one swirl and pops out of its twin on the same heading, carrying the light across gaps a cushion would otherwise block. Boards grow from a tidy 5x5 up to a busy 10x10 as you go.
There is no timer, no move limit, and no way to lose - Beam is a calm, take-your-time puzzle. Every board is built backward from a guaranteed solution and re-checked before you ever see it, so you can experiment freely knowing a real answer always exists. Clear all 20 levels and Endless mode opens up, generating brand-new boards with every mechanic switched on from the first one and difficulty that keeps ramping past the curated finale, so the puzzles never run out.
How to play Mochi Beam
- Spot the smiling mochi lamp on the edge of the grid - that is the emitter, and it fires one beam inward in a single fixed direction.
- Tap any bright candy mirror to flip its diagonal bar between its two angles; the glowing beam re-routes the instant you do, so you always see exactly where it goes.
- Bend the beam so its path runs through every crystal on the board - each crystal lights up and sparkles the moment the beam crosses it.
- On later worlds, drag a mirror that sits on a slide rail (look for the chevrons) along its groove to the cell where it bends the beam correctly - its angle is fixed, so it's a position puzzle.
- Light every crystal at the same time to clear the level, get your three stars, and unlock the next puzzle.
- After level 20, choose Endless to keep solving freshly generated boards for as long as you like.

Tips & strategy
- Work backward from a crystal you still need to light: figure out which direction the beam must arrive from, then set the nearest mirror to send it there.
- Watch the whole beam, not just the crystal you're aiming at - flipping a mirror to catch one crystal often swings the beam off one you already lit, so lighting them all at once is the real challenge.
- Sleepy cushions and bolted mirrors never move; treat them as fixed walls and plan your bounces to flow around their angle.
- Bolted mirrors look dim and have little bolts at each end, and tapping them does nothing - recognising them early saves wasted taps.
- For a rail mirror, drag it slowly and watch the live beam: the right slot is wherever the light suddenly snaps toward your crystals.
- When a board has a portal pair, the beam leaves the twin swirl on the exact same heading it entered - use that to leap across a cushion wall instead of going around it.
- Every board starts with exactly one piece already in its solved state and the rest scrambled wrong, so the opening position is close to solved on purpose; look for the small set of changes that finishes it.
- Nothing is timed and you can flip mirrors as many times as you want, so try things freely - every Mochi Beam board is guaranteed to have a solution.

Frequently asked questions
How do I actually win a level in Mochi Beam?
Steer the single beam so its path runs through every crystal on the board at the same time. A crystal lights up while the beam crosses it, and the level clears the instant all of them are lit together - there is no points target, just light them all.
What's the difference between tapping a mirror and dragging one?
Most mirrors rotate: tapping flips the diagonal bar between its two angles, forward-slash and back-slash. Rail mirrors are different - they sit on a slide track marked with chevron arrows and keep a fixed angle, so you drag them along the groove to the right cell instead of flipping them. Bolted (dim) mirrors with bolts at each end can't be changed at all.
What do the cushions and portals do?
The sleepy pillow cushions stop the beam dead, like walls, so you have to route the light around them. Portal pairs are linked swirls (each pair tinted its own colour so you can tell which two are joined): the beam dives into one and re-emerges from its twin on the same heading, which lets it cross gaps a cushion would otherwise block.
How many levels are there, and what is Endless mode?
There are 20 hand-tuned levels split into five candy worlds - Berry, Citrus, Mint, Ocean, and Galaxy - four levels each, with boards that grow from 5x5 up to 10x10. Clear all 20 and Endless mode unlocks, generating new boards forever with every mechanic active from the very first endless board and a difficulty that keeps climbing past the final curated level instead of resetting easy.
Can a Mochi Beam puzzle ever be impossible?
No. Every board is built backward from a known solution: the beam is walked across the grid first, mirrors and crystals are placed on its path, then the whole thing is re-traced to confirm every crystal still lights before you ever see it. The mirrors are only scrambled afterward, so there is always at least one valid way to solve it and you can never get genuinely stuck.
Can I keep re-aiming the beam forever, or is there a shot or move limit?
You can re-aim as much as you like - there is no timer, no shot limit, and no cap on how many times you flip or slide a mirror. The board even counts your taps and shows the total on the clear card ("Lit up in 7 taps!"), but it's just a curiosity: clearing a level always awards the full three stars no matter how many flips it took, and a wrong move never fails you.
Does Mochi Beam remember which mirrors I have flipped if I leave mid-puzzle?
It remembers which levels you have cleared and reopens at your highest unlocked one, but it does not save a half-finished board - your individual flips and rail slides aren't stored. Stepping away and coming back reloads that puzzle from its original scramble (one mirror already set correctly, the rest wrong), so you start that level fresh. Unlocks and stars are kept privately in your own browser on this device; a different device or browser begins a new save.
