Under Construction Ext
Read full descriptionHide full description
This is a construction site. It is a game to fill all the stones in the hole. The bulldozer can only push the stone forward. Operate the bulldozer well and move the stone to the hole position. To move the bulldozer, drag the movement path with your finger from the position of the bulldozer. The route is displayed as a red line, so release the finger and the bulldozer will start moving. If you notice a mistake before releasing your finger, it will be canceled if you do not move your finger for 3 seconds.

ACE TOWER — THINK. PLAY. CLIMB. ACE TOWER is a strategic card puzzle where every placement changes what comes next. Draw cards one at a time and place them across multiple rows. Build valid combinations, manage your limited space, and lock each row in the right order. Every decision changes the board—and one careless move can leave you without a legal solution. CLIMB THE JOURNEY Begin your climb across 45 progressive floors, with increasingly demanding score targets, new combinations, and tougher strategic decisions. Earn one, two, or three stars on every floor, improve your personal best, and keep climbing as ACE TOWER continues to grow. PLAN. MOVE. LOCK. Think several moves ahead. Reposition cards while space remains, decide when a row is ready to lock, and build stronger combinations as you climb. Success comes from finding the right sequence—not from luck. TOOLS FOR BETTER SOLUTIONS Use Undo to reconsider a decision and refine your strategy. Unlock guided Solver solutions for different star targets, study the sequence, and then return to beat the floor yourself. DISCOVER HOW YOU PLAY Your Player Profile tracks your decisions across eight distinct playing styles. See the patterns behind your choices and discover how your approach develops over time. PLAY YOUR WAY • Journey: Climb progressive floors and earn up to three stars. • Playground: Experiment with different deck sizes and play without floor objectives. • Compete: Unlock asynchronous 1v1 strategic challenges as you climb. QUICK TO START. DIFFICULT TO MASTER. Play a floor in a few minutes or stay for a deeper strategic run. Every attempt is another chance to rethink the board, find a stronger sequence, and surpass your best score. Do you have what it takes to reach the top? Download ACE TOWER and start climbing.
