Dokamori Mont Blanc Simulator is a free browser game where you pipe chestnut or purple-sweet-potato cream and stack chestnuts and sweet-potato pieces into a towering Mont Blanc dessert. If height is your goal, start with the developer's clearest hint: aim at the center to stack decorations upward.
A Mont Blanc cake normally belongs in a pastry shop. Give this one a few extra layers and it begins to resemble a construction project with a delicious building permit. The fun is in choosing whether to make a beautiful dessert or a frankly unreasonable tower.
The game was officially released on October 21, 2026. It lets you rotate your creation and save an image that includes its height.
1. Where to play
Play Dokamori Mont Blanc Simulator.
The interface offers four materials: chestnut cream, sweet-potato cream, whole chestnuts, and cut sweet potato. It needs a WebGL-compatible browser. The official instructions cover both touch gestures and mouse controls. This is primarily a freeform decorating experience rather than a conventional level-by-level challenge.
2. Controls: pipe, place, move, rotate
- Pipe cream: choose chestnut or sweet potato, then press and drag. The changing shape of each piping bag indicates how much remains.
- Place toppings: select a chestnut or cut sweet potato and tap where it should go. Aiming toward the center lets you stack toppings higher, according to the game's instructions.
- Move a topping: use the hand icon to grab and reposition decorations. Tap it again to return to the selected material.
- Rotate the cake: with the hand tool active, drag over an empty area in any direction. The automatic-rotation button cycles through speeds, and you can keep decorating while it rotates.
- Zoom: pinch with two fingers on a phone or use the mouse wheel on a computer.
When the controls feel unresponsive, check whether you are in topping mode or hand mode before trying again.
3. A practical height-building experiment
There is no verified world-record strategy in the official instructions. The following is a repeatable approach to try, not a proven optimal build:
- Pipe a modest cream base and check the bag indicators before using everything.
- Place a chestnut or potato piece close to the center, where upward stacking is supported.
- Build several layers, then rotate the camera and inspect from the side.
- Use the hand tool to adjust decorations that appear out of line.
- Finish, save the height-labelled picture, and compare your next attempt.
The documented mechanic is center-targeted stacking. Whether a particular layout produces a taller final cake is something players can test rather than assume.
4. Making it look good instead
A maximum-height attempt can turn the dessert into a chestnut radio mast. For a prettier result, experiment with the color contrast between brown chestnut cream and purple sweet-potato cream. Put accent toppings where they remain visible from multiple angles.
Try a chestnut near the top and pieces of sweet potato along the visible sides. These are decorating suggestions, not claims about hidden score bonuses. Rotate often: a gorgeous front view can conceal a very questionable back.
5. Saving your finished Mont Blanc
Press Finish (the Japanese interface reads “できあがり”) to reach the completion screen, where you can save or share an image showing the creation's height. When sharing to X, attach your saved image to the post.
Creations are not automatically saved. Save an image before closing the page. Starting a new cake removes the current creation; the game shows a warning before that happens. The completion screen also offers a way back to editing.
6. Frequently asked questions
Is there an official leaderboard or maximum height? The official page describes a height display, but the instructions checked for this article do not specify an official leaderboard, maximum record, or guaranteed winning method.
Is cream unlimited? The piping bags visibly indicate remaining amounts, so watch both instead of assuming endless supplies.
Can I continue tomorrow? The game does not advertise automatic restoration of a closed session. A saved picture preserves your result, not an editable cake.
7. The real challenge
Beautiful pastry or towering absurdity? You decide. Four simple ingredients create an unexpectedly serious question: “Surely one more chestnut will fit?”
It starts as dessert design and ends as edible-looking structural engineering. Remember the screenshot; your masterpiece won't save itself.
