Just use your mouse. Left click grabs items from the menu and drops them into your room. Scroll to browse the catalog faster. Pro tip: hold shift while clicking to place items in a perfect grid line instead of guessing the spacing.
TB World is a casual sandbox game focused on character design and room decoration. You get a blank room and a big catalog of furniture, wallpapers, and decorations to place. The game hands you tools to customize everything down to tiny details. Honestly, the room decoration part is solid, but the character creator feels a bit limited after your first hour of playing. The vibe is very cute and colorful. It's a desktop browser game built for people who just want to relax and build something without pressure. Fans of cozy games will like it.
If you want a logic break from decorating, Sudoku Block Puzzle is a fun puzzle to try.
Load the game and you start with an empty room. Open the decoration menu on the right side of the screen to pick furniture and drag it onto the floor. You can rotate items and move them around until the room looks right. The first room takes about 10 minutes to fill up nicely. Later on, you unlock more items and bigger rooms to decorate. The main loop is just earning new decorations by spending time in the game. The menu loads a bit slow when you own over 50 items, which gets annoying. Just plan your layout before opening the catalog.
When building rooms gets too chill, Brainrot Tower Defence adds some fast strategy action.

Common questions about TB World
The game only works on desktop browsers right now. The click and drag controls need a mouse. Mobile support might come later but isn't available.
Local save stores your progress in the browser cache. Clearing your browser data deletes everything. Make a free account to back up files online.
Five save slots are available from the start. Each slot holds one complete room layout with all placed decorations and your custom character.
All items unlock through regular gameplay. No real money purchases or premium currency exist in the game. Just play to earn new decorations.
The game lacks a direct share button right now. The only option is taking a screenshot and sending that to friends.
Large rooms with over 80 placed items can drop the frame rate on older computers. Try removing animated objects or closing other browser tabs.

Pick this if you want a relaxed building game that doesn't nickel-and-dime you. Unlike other browser sandboxes, every decoration item unlocks through normal play. The catalog has some gapsโthere are only 4 wall colors at launchโbut the core building tools work well and the controls are simple enough for kids to understand.
