Wolfoo Bento Master is a free cut-and-fit puzzle: each level gives you a bento box with differently shaped compartments and a few pieces of food — rice, fruit, vegetables. You may only slice along the direction the level allows (horizontal, vertical or diagonal), cutting pieces to size, then drag and rotate them to fit snugly and fill every compartment 100% with nothing left over and no gaps. Slice the wrong way and the knife dims; place a piece badly and you simply lift it out again — no penalty. Fewer direction changes and no gaps earn more stars. Safe for kids 4-10.
The game folds three geometry ideas into one familiar action: area (will this piece fill the compartment?), division (how do I cut it to size?) and rotation (a shape stays the same shape when turned). Being limited to one cutting direction forces kids to plan before they slice rather than slice and fix. The star rating rewards tidiness, not speed, so there is room to think slowly. No timer, no failing, no penalties. Free, inside the parent-controlled Wolfoo environment.
