Fill the box. Leave no gaps.
Obento Puzzle is a single-player puzzle about packing a bento lunch box. Each dish is a piece made of joined squares: a cherry tomato is a single square, a sausage is two in a row, fried chicken is a T shape, and a rice ball is a two-by-two block. Your job is to fit every piece into the box without overlaps and without leaving a single empty cell.
A round takes about one to three minutes. The game is designed for a phone held upright and played with one hand, and it runs in a web browser, so there is nothing to install.
How to play
- Drag: Carry a piece from the tray into the box. Pieces snap to the grid. If you let go where the piece does not fit, it returns to the tray.
- Tap: Rotate a piece 90 degrees clockwise. Pieces can be rotated but never flipped over.
- Drag out of the box: Send a placed piece back to the tray.
- Undo and reset: Undo is unlimited and free. Reset returns every piece to the tray.
A puzzle is solved when every piece is in the box, nothing overlaps, nothing sticks out, and no cell is left empty. Only the final board is checked, so any arrangement that fills the box counts, even if it differs from the one the puzzle was built from.
Two ways to play
- Stages: Numbered stages that grow step by step, from a 3 by 3 box with a few small pieces to boxes up to 6 by 8 with more than ten pieces. From stage 101, five-square pieces join the mix. Stages are generated as you play, so there is no fixed last stage, and you can replay any stage you have cleared.
- Today’s Bento: One daily puzzle that everyone plays on the same date, switching at midnight Japan time. It has no time limit, and you can share your result, which shows your stars and time but never the solution.
Stages have a time limit, shown as a bar above the box. The limit is generous up to stage 30 and grows tighter after that. Running out of time only means trying the same puzzle again from the start; you do not lose your records or unlocked stages. The clock pauses while the game is in the background.
Tips for a tidy box
Every puzzle is created by first cutting the box into pieces and then shuffling them, so each one has at least one solution. A few habits help you find it.
- Place the awkward shapes first. Long straight pieces and T, S and Z shapes have fewer places to go. Single-square pieces are the easiest to fit last, into whatever gap remains.
- Watch the corners and edges. A one-cell gap trapped against the wall can only be filled by a piece that has a square in exactly that spot. Check what the leftover space will look like before you commit.
- Count the squares. The pieces always add up to the area of the box. If the space you are leaving cannot be split into the shapes still in the tray, back up with Undo.
- Use hints with care. A hint places one piece in its correct position and locks it there. Each puzzle includes one free hint, but using a hint removes a star.
Clearing a stage earns one to three stars based on how much time is left: three stars with at least half the limit remaining, two with at least a fifth. In Today’s Bento, stars depend on how many hints you used. A top-10 ranking lists the highest stage reached and the fastest hint-free clears of the day, without user names.
