Mochi Monsters Review: A Color Sort Puzzle With Lids, Tides and Hats
Sixty levels, three worlds, a shop full of tiny hats and a panda who keeps hopping onto the wrong nest.

Yes, Mochi Monsters is a color sort puzzle, and a gentle one: you hop squishy monsters between glass nests until each nest holds a single species. If you like water sort or ball sort puzzles, you already know the idea. The twist is that the colors have faces, and the faces have opinions.
I am Polarzinho, the studio panda, so I am biased: this is a Polar Games title and I would defend it in a parking lot. I also played it properly: all 60 levels, one dead end on level 6, the beach tricks, twelve levels of endless mode and every hat in the shop. I played in English, so the screens below are in English too.
A color sort puzzle where the colors have faces
The game opens on a pastel meadow with lollipops the size of trees and a pink blob named Momo, your host. There is no sign-in: you click once, Momo says hi and you are playing. The menu is short: a big Play button that shows your level, then Levels, Album and Shop, with the settings gear at the top right and your Sugar Drops at the top left.
How a color sort puzzle works, and what Mochi Monsters changes
A quick primer. A row of containers holds mixed colors, and you move colors around until each container holds just one. Two rules keep it honest: you can only drop onto the same color or into an empty container, and there has to be room. That is why empty containers are the whole game.
Mochi Monsters keeps the rules and changes the costumes. The containers are glass nests with a little woven basket at the bottom, and each holds four Mochis. The colors are species: pink Momo, blue Bloop, yellow Pippin, green Sprig, purple Zuzu and a few more later. Two or three of the same species on top hop together as one group. Compared with a plain water sort or ball sort game, you also get:
- Characters instead of liquid: Sprig has a leaf, Ember a flame, Zuzu a star on an antenna, so color is not the only clue.
- Momo's hint, with a little hand showing where to start and where to drop.
- Worlds with their own rules: shell lids on levels 21 to 30, tide nests on levels 31 to 40.
- An album of friends, a garden and a hat shop paid in Sugar Drops.
How to play Mochi Monsters: tap a nest, tap another, hop
The tutorial is one small board: two species, three nests. Tap a nest and the group on top lifts, the nest glows and a hand points at the empty one. Momo explains: “Tap one nest, then another. They can only hop into an empty nest or next to a matching friend!” I finished the tutorial and Momo paid me 50 Sugar Drops.

PolarzinhoA halo around a nest. I have never been this respectful to furniture.
- Tap or click a nest to pick up the group on top.
- Tap an empty nest, or a nest whose top Mochi is the same species and has room.
- Repeat until every species has a full nest of four. Finished nests get a daisy.
Try a hop the rules do not allow and nothing moves. The Mochis you tried to place squeeze their eyes shut and Momo looks startled.

PolarzinhoI asked a blue Mochi to sit on a pink one. Everybody reacted like I had asked to sit on their lunch.
On a keyboard, the arrow keys move a highlight across the nests and Enter picks up or drops a group. H asks for a hint, Z undoes, R restarts and Esc pauses. I tried every one and they do what they say.
Sugar Meadow: twenty levels of learning to love the empty nest
The first world is pink, sunny and patient. Levels 1 to 5 use three species in five nests. From level 6 you get four species in six nests until level 20: sixteen Mochis and two spare nests. While you play, the screen shows only the world, the level and your Sugar Drops. No timer, no move counter. Your hop count shows up after you win, which I appreciated, because I would have counted them anxiously and cried.
A win lights the nests gold, puts a daisy on every full nest and lets Momo say Amazing!, So squishy! or You did it! Early levels paid +30 Sugar Drops. Every fifth level adds 40 on top, so level 5 paid +70 and level 20 paid +76.

PolarzinhoFour daisies, two empty nests and a pink blob who looks proud of me. I accept this bouquet.
Hint, Undo and Restart: Momo's rescue kit
Undo, Restart and Hint sit at the bottom of every board. Press Hint and Momo's bubble gives a line of advice, one nest glows lilac, the destination glows orange and a hand points where to tap. It cost me nothing: my Sugar Drops read 50 before and after.

PolarzinhoFree the ones underneath. Momo, that is a motto, not a hint. Fine, it is both.
Then came level 6. I made three confident hops and the bubble answered: “No hops left. Undo or restart?” I had parked one pink Mochi and one yellow in my two spare nests, and three full nests were topped with purple Mochis with nowhere to go. I pressed Hint, hoping for a miracle. Momo said: “Momo is not sure right now. Try Undo or Restart.” My host. My friend. I pressed Undo, then Restart, and cleared it in 12 hops.

PolarzinhoThree hops from a dead end. The game saw it before I did, which is rude and also useful.
My friend Noodle from the studio chat leaned over my shoulder and said the empty nests were right there. They were. I had filled them. We agreed never to speak of it.
Bubble Beach: shell lids and tide nests
Level 21 swaps the meadow for a sandy beach and, more importantly, new rules. A pop-up titled Shell lids says: “Fill a nest with Momo to open the lid. Undo may close it.” On the board, one nest wears a seashell with a picture of a Mochi and a padlock.

PolarzinhoI asked the padlocked nest to take a Mochi. It said no, politely, with a seashell.
The lid works like a bouncer. My hop onto the locked nest went nowhere, and Momo reminded me: “Focus on the friend shown on the lid.” Once I filled a nest with the pink Momos, a daisy popped on top of it, the shell vanished and the locked nest opened for business. Levels 21 to 30 all use lids, with a different species on the shell now and then.
Level 31 brings the second trick, with its own pop-up: Tide nests. “Linked nests swap places when one of them becomes empty.” Two nests carry ring badges joined by a dotted line. I emptied one and the pair swapped, like furniture rearranging itself: the empty slot jumped to where its partner had stood. The empty nest you were counting on suddenly lives somewhere else.

PolarzinhoA dotted line between two nests. Anything joined by a dotted line is about to ruin a plan.
Mushroom Village and the endless mode
Level 41 drops you into Mushroom Village: pink clouds, mushroom-roof houses and a little waterfall behind the nests. I found no new gadget there, just bigger boards: levels 41 to 50 have five species in seven nests, and levels 51 to 60 have six species in eight nests. Clearing level 60 paid +90 Sugar Drops and introduced a friend called Minty. Then Next took me to Endless 1 instead of a level 61.

PolarzinhoEight nests, twenty-four Mochis, one panda trying to look calm.
Endless mode sits at the bottom of the Levels screen. Early on it is greyed out with a note asking you to finish level 20. My boards were plain: four species in six nests for the first ten, five species in seven nests from Endless 11, no lids, no tides. Rewards followed the campaign's scale, +36 for Endless 1 and +80 for Endless 10. After twelve levels the Play button read Endless 13, and I stopped, because even a panda has to eat.
Album, garden and the hat shop
Sugar Drops go to Momo's Hat Shop, the only place I found to spend them. Six hats: Ribbon Bow 150, Daisy Clip 220, Leaf Cap 300, Strawberry Hat 420, Star Clip 600 and Little Crown 900, 2,590 for the full set. By level 60 I had earned 2,890, tutorial included, so I bought every hat and had 300 left to look at proudly.
In the garden, tap a friend, read the one-line description, then press the Hat button to cycle through what you own. As far as I could tell, hats are only for looks, and I did not mind. Tutti copied Momo's Ribbon Bow, and I let it.

PolarzinhoZuzu naps under the stars, so the crown fits the job description.
The Mochi Album gives every friend a short bio. Bloop is curious about everything and leaves tiny drops when excited. Minty is shy at first, then the best friend ever. The win screen announces a new friend whenever a species debuts: Sprig after level 1, Ember after level 20, Tutti after level 41, Minty after level 60. My album read 8 of 10 friends, with two silhouettes still waiting.
Languages, settings and phones
The settings, from the gear on the menu or the pause menu, offer 14 interface languages, from Português (Brasil) and Español to 日本語 and 简体中文. I flipped to Portuguese and Spanish to check, and everything changed at once: Jogar, Fases, Dica and Desfazer in Portuguese, Jugar, Niveles, Pista and Deshacer in Spanish. The game page lists desktop and mobile; I played on desktop, and my level and Sugar Drops were still waiting after I reloaded the page.
Tips for any color sort puzzle, tested on Mochi Monsters
- Guard the empty nests. Two spares feel like plenty until you park a single Mochi in each, which is how I died on level 6.
- On lid levels, go for the species on the shell first. The lid opens once a nest holds a full set of it.
- Use Z freely. The game warns that Undo may close a lid again, but undoing never cost me a single Sugar Drop.
FAQ
Is Mochi Monsters a water sort game?
It belongs to the same family as water sort and ball sort: you move groups between containers until each holds one kind. Here the containers are nests, the kinds are Mochi species and groups hop together.
How many levels does it have?
Sixty, in three worlds of twenty: Sugar Meadow, Bubble Beach and Mushroom Village. Endless mode opens after level 20 with new puzzles.
Is there a timer or a move limit?
I saw neither. While you play, the screen shows only the world, the level and your Sugar Drops.
Does the hint cost anything?
Not that I could see: my Sugar Drops did not change when I pressed Hint.
What are Sugar Drops for?
You earn them by winning levels and spend them on hats in Momo's Hat Shop. The hats show up on your friends in the garden.
Mochi Monsters pros and cons
Ready to find every Mochi a nest?
Mochi Monsters is on Polar Games, straight in your browser. Tap Play, let Momo walk you through the first board and keep one nest empty for as long as you can. If a level eats you alive, I will bet it was level 6.
