Mochi Bridge

Wire up every numbered candy island with the exact count of straight, never-crossing bridges until the whole scattered archipelago snaps into one connected, glowing network.

About Mochi Bridge

Mochi Bridge is a candy-coated build of Hashiwokakero, the Japanese pencil puzzle better known in English as Bridges or Hashi. Each board sprinkles a handful of glowing islands across a grid, and every island wears a number from 1 to 8: the exact count of bridge ends that must meet it when the puzzle is done. You connect islands with straight horizontal or vertical bridges, and two islands that share a row or column can be joined by either one bridge or two. Drag from an island to an in-line neighbour, or tap the empty span between two of them, and that link cycles up through one bridge, then two, then clears back to none, so adjusting a guess is just one more tap.

Two hard rules make every layout deductive rather than fiddly. Bridges may never cross one another, and they can never run straight over a third island, so a long span you commit to in one direction can quietly forbid a perpendicular one somewhere else. On top of satisfying every number, all the islands have to finish wired into a single connected group, with no small cluster sealed off on its own. Try to draw a bridge that would cross an existing one and the move is refused with a little red shake and a buzz; over-fill an island past its number and it flashes red so you know to cycle one of its links back down.

There are no timers, no lives, and no fail state, so this is a sit-back, think-it-through puzzle rather than a reflex test. Every level is generated by growing a real, connected solution first, sprinkling in some extra legal bridges for richness, then numbering each island from that finished plan, and the whole thing is re-checked for matching degrees, full connectivity, and zero crossings before it ever loads. That means a clean answer is always guaranteed to exist, even out in the endless run. When the last bridge clicks into place the islands turn mint-green, pop a check tick, and burst into a three-star sparkle.

The 20 hand-tuned levels are split into five candy worlds, Berry, Citrus, Mint, Ocean, and Galaxy, four puzzles apiece, each with its own colour palette and night-sky backdrop. World 1 keeps you on a roomy 5x5 grid with only five or six islands to teach the rule; by World 5 you are untangling roughly twenty islands across a packed 10x10 grid. Clearing a level unlocks the next, and finishing the curated set opens an endless stream of fresh puzzles that starts at finale-level difficulty and keeps climbing.

How to play Mochi Bridge

Look at the number on each candy island: that is how many bridge ends must touch it once the board is solved (Hashi numbers run 1 to 8).
Drag from an island toward an in-line neighbour in the same row or column, or tap the empty gap on the line between two such islands.
Each drag or tap cycles that one link: none to a single bridge, to a double bridge, then back to none, so you can dial it up or undo with the same gesture.
Keep bridges straight and clear: a link that would cross an existing perpendicular bridge, or one dropped on an island that is not actually in line, is refused with a red shake.
If an island flashes red you have over-bridged it past its number, so cycle one of its links back down a step.
You win the moment every island's number is matched and all the islands are joined into one single connected network, which lights up a three-star celebration.

Controls

Input	Action
`Drag island to island`	Cycle the link between two in-line islands: none, one bridge, two bridges, then back to none
`Tap the gap`	Tap the empty span on the line between two in-line islands to cycle the same link
`R key`	Restart the current puzzle, clearing every bridge back to an empty board
`Settings (gear)`	Open the panel to restart, jump to level select, or mute the sound
`Space` / `Enter`	Advance to the next puzzle from the level-complete card

Tips & strategy

Hunt for forced moves first. An island showing 1 or 2 that has only one possible in-line neighbour can be filled immediately, because its bridges have nowhere else to go.
Numbers that fill their space lock in fast: an island with few neighbours but a high number must run doubles to most of them, so place those before anything ambiguous.
A double bridge maxes a link at two, so an island marked higher than twice its neighbour count is impossible by definition, and reading that ceiling rules out a lot of guesses.
Watch crossings before you commit. Because bridges can never overlap, drawing one long span often quietly forbids a perpendicular bridge you were counting on elsewhere.
Do not forget the connectivity rule. Even with every number satisfied, the puzzle is not won until all islands link into one group, so avoid sealing a corner cluster off by itself.
When an island flashes red it is over-bridged: cycle one of its links down rather than tearing up the board, since one tap fixes it.
Tapping the gap between two islands is often quicker than dragging on a crowded board, and it cycles the exact same link.
Stuck? Restart from the gear menu costs nothing here, and a clean board frequently makes the early forced moves jump out again.

Game features

A full Hashiwokakero (Bridges / Hashi) ruleset: numbered islands, one-or-two bridges per link, never crossing, never over an island, all wired into one connected group.
20 hand-tuned puzzles across five themed candy worlds, Berry, Citrus, Mint, Ocean, and Galaxy, four levels each with their own colour and starry backdrop.
A difficulty curve from cosy 5x5 boards of five islands up to dense 10x10 archipelagos of around twenty.
An endless mode unlocked after the curated set that generates fresh puzzles, starting near the hardest curated board and ramping the grid and island count from there.
Every puzzle is grown from a genuine solution and re-validated for matching numbers, full connectivity, and zero crossings before you see it, so a clean answer always exists.
Forgiving, no-fail design: no timer, no lives, instant undo by cycling a link down, and a one-key full restart.
Clear visual feedback: islands glow mint-green with a check tick when satisfied, flash red when over-bridged, and refuse illegal crossings with a red shake.

Frequently asked questions

What is Hashiwokakero, and is that what Mochi Bridge plays like?

Yes. Hashiwokakero, also called Bridges or Hashi, is a Japanese logic puzzle where you join numbered islands with straight bridges so each island gets exactly its number of bridge ends, no two bridges cross, and every island ends up in one connected group. Mochi Bridge follows that ruleset exactly, just dressed in glowing candy art.

How many bridges can connect the same two islands?

At most two. Each link between two in-line islands cycles none, one bridge, two bridges, then back to none, so a pair can never hold three or more. That cap is why an island marked higher than twice its number of neighbours is unsolvable, which is a handy thing to spot.

What exactly counts as winning a level?

Two things have to be true at once. First, every island's bridge count must equal the number printed on it. Second, all the islands must be joined into a single connected network, with nothing floating off on its own. Hit both and the board sparkles to a three-star finish.

Can I make an illegal move or lose the puzzle?

There is no losing. A bridge that would cross another, or one dropped on an island that is not truly in line, is simply refused with a red shake. Over-fill an island and it flashes red so you can cycle a link back down. Nothing is ever locked in, and there is no timer.

How many levels are there, and what is endless mode?

There are 20 hand-tuned levels across five worlds (Berry, Citrus, Mint, Ocean, Galaxy), ramping from 5x5 boards of about five islands to 10x10 boards of around twenty. Clearing all twenty unlocks an endless mode that generates new puzzles starting at the hardest curated difficulty and climbing the grid size and island count from there.

Are the generated puzzles always solvable?

Always. Each board is built by first growing a real connected solution and then numbering the islands from it, and the result is re-checked for matching numbers, full connectivity, and no crossings before it loads. If a generation attempt ever fails the checks, it is discarded and another seed is tried, so an unsolvable board never reaches you.

Is my progress saved between sessions?

Yes, in your browser. Mochi Bridge stores which levels you have unlocked and your stars locally, so the next world stays open when you come back. It plays the same with drag-and-tap on phones, tablets, and desktop, with no download or account needed.
