Stackadel: Tower Challenge

Build high. Stay steady. Don't let it topple!

Stackadel is a cozy physics stacking puzzle. Falling bricks land with real weight. They tilt, slide and wobble, so every drop counts. Guide each brick, spin it into place, and raise your castle's tower past the finish line before too many bricks tumble off the edge.

🏰 Campaign: the Tower Trail

200 towers across 23 districts. Start in Mint Meadow and Coral Harbor, then climb through Cloud Citadel, Frostpeak and Sakura Hills all the way to the Dragon Throne.

Each tower has its own height goal, fall speed and drop limit.

Earn up to 3 stars and collect coins for every tower you clear.

Weather changes the game. Sunny days are calm, rain makes bricks slippery, and wind pushes your tower sideways.

♾️ Endless Tower

How high can you build?

You have 3 hearts, and every lost brick costs one.

Bricks fall faster the longer you survive.

Place bricks without losing any to chain combos up to x3.

Chase your best height. A marker line shows your record in the world as you build.

✨ Boosters

Freeze: anchors the bricks already on your tower.

Slow Fall: slows falling bricks for 60 seconds.

Reroll: swaps all three upcoming bricks.

Spend the coins you earn in the Booster Shop.
