LoopBoo / TowerBoo
Stack falling blocks into a wobbly tower
Play soloA tower stacking puzzle with real physics: four-block pieces fall over a narrow platform, and the moment one lands it can slide, tip and topple. Build a steady tower up to the finish line before you run out of lives. Race the clock solo for the leaderboard, or race friends with the same pieces.
TowerBoo is our tower stacking puzzle with real physics. Four-block pieces – the long bar, the square, and the T, S, Z, L and J shapes – fall one at a time over a narrow stone platform. While a piece falls it is yours: move it column by column, turn it a quarter at a time and drop it faster when you are sure. The moment it touches the tower, it lets go and real physics takes over.
A block that lands flat sits still. One that hangs over an edge leans, tips and may slide off; a heavy piece on a thin tower makes it wobble. Every piece that falls off the platform costs one of your three lives. Your goal is the finish line, fourteen rows up: get your tower there and keep it standing for two seconds.
Falling block puzzles are a classic: turn the pieces, fit them together, keep the stack tidy. A physics tower game turns that idea upside down. Nothing clears and nothing snaps into a grid once it lands: every block keeps its weight, its friction and its balance, and a tower has to stand up by itself. That makes each piece a small decision – flat and safe, or tall and risky.
TowerBoo is free in your browser, with no sign-up and nothing to install. Solo races go on a leaderboard with Today, Week, Month and All time views. In Duo and Group rooms, friends join with a code or a link and race the same pieces in the same order, watching each other’s towers rise as they play. TowerBoo comes in eleven languages, in light and dark.
TowerBoo suits anyone who likes a quick, lively puzzle with a bit of tension, and anyone who likes to build. It trains spatial thinking – seeing where a shape fits before it lands – and a feel for balance: how much a tower can hang over, and when a wide, steady base beats a fast, thin climb.
Pieces come in shuffled sets of seven, so every seven pieces bring one of each shape: a long bar is never far away. A game left half-played comes back where it was after a reload, with every block where it lay.
Fit the blocks, clear the lines
A block puzzle on an 8 × 8 board. Three pieces at a time: fit them in wherever they go, and every full row or column clears. Clear several lines at once, or on piece after piece, for big points. Play solo for the leaderboard or race friends on the same pieces.
Merge fruits, make a watermelon
The fruit merge game. Drop fruits into the box: two of a kind that touch become the next fruit up, from cherry to watermelon. Keep the pile under the line as long as you can. Play solo for the leaderboard or race friends with the same fruits.
Shoot animals, merge them round the ring
An animal merge game on a ring: shoot cute animals out from the middle, knock them along the ring and merge two of a kind into the next one up, from mouse to elephant. Keep the ring from filling up. Play solo for the leaderboard or race friends with the same animals.
Slide, merge, make 2048
Our take on 2048. Every tile on the 4 × 4 board slides at once: two equal tiles that meet merge into their sum. Keep merging up to 2048 and beyond before the board fills up. Play solo for the leaderboard or race friends on the same tiles.
