Stackdle – Play the Daily Stacking Game Online

Stackdle is a daily stacking game by Amountle, whose creator Isaac Audet also makes other daily browser puzzles. Its challenge is physical: each shape needs a stable place on the current structure, and its orientation changes how it will rest after release. Height is the score. The daily limit of twenty pieces creates a balance between reaching upward and preserving enough support for later moves. Three falls give you a small amount of recovery, while the settling step separates an ambitious-looking placement from a tower that actually stands. Practice uses the same aiming and dropping ideas with endless pieces and retries. Undo and restarting the same pieces make it possible to compare placements without immediately changing the sequence. Starting a new practice set shifts the challenge to a different combination of shapes. The board supports both pointer and touch interaction. Upcoming-piece previews help with planning, and camera controls remain useful after the tower grows. A strong approach is to inspect the contact surfaces, release one piece, wait for the result and adjust the next move to the structure that remains.

Click Play Now above to open the board, then choose Daily or Practice. Daily gives you a limited run with up to twenty pieces and three falls. Practice is useful when you first want to understand how a piece moves, rotates and lands, because it provides endless pieces and retries. Position the active piece over a part of the tower that can support it. Drag it or use the horizontal arrow keys, then rotate it with the handle, mouse wheel or keyboard controls. On a touch screen, sliding nudges the piece and a two-finger twist turns it. The board remains steady while you aim, so take time to examine the piece's contact points. Check the next-piece preview before making a difficult placement. Its actual-size view helps you judge how much room a shape needs. A flat base can be easier to support than an angled edge, while a small adjustment may change which parts touch the tower. The ninety-degree rotation control is a quick way to compare orientations before making finer turns. Drop the piece when you are satisfied with the position. Let the movement finish: the tower has to settle before its new height counts. The result is measured in centimeters, so the objective is to build higher while keeping the structure stable. A risky position that immediately topples does not provide a reliable way to increase the score. If a piece falls in Daily, the game retries from the last steady tower and spends one of your limited fall opportunities. Reassess the placement before dropping again. In Practice, use Undo to try a different decision, Restart to revisit the same sequence, or New practice set when you want different pieces. As your tower grows, use the camera tools to keep the active area visible. Zoom, Move Camera and Fit whole tower change your view rather than repositioning a block. Separating camera adjustment from piece placement helps you keep control when the structure becomes taller than the first screen.
