Tower puzzles: reverse echo, binary weights and Hanoi

In the logic room, right-click on the lectern or “Open Puzzle” in /tower. First, open the “Rules”: similar boards have different conditions, but there is no ready-made code for all run.

Endless Tower labyrinth. On other floors there are separate boards with puzzles.

Find a puzzle and save your attempt

For rooms without combat, select /tower join peaceful. In addition to logic, there are parkour, traps and labyrinths; it is not a direct selection of one puzzle.

"Start Puzzle Over" returns the original state of the same option. Returning to the tower menu only closes the board. For a break, use /tower pause, then /tower resume for 15 minutes; “End run” cancels the continuation.

General rules of run and the difference between final exit and break. Pause, upgrades and floors.

Reverse echo and color code matching

In reverse echo you need to play the show from the end. Case Study: Red → Blue → Yellow becomes Yellow → Blue → Red. If you forgot the sequence, run a replay rather than guessing the last clicks.

In the color code task, click to change the color of the item, then click “Check”. The answer tells you the number of colors in their places and the correct colors in other places. Save the result of the test and change a small part of the code: otherwise it is difficult to understand what improved the answer.

Sum and binary weights

In the regular amount, you can select and remove numbers by clicking again. Start with large numbers that don't exceed your goal, then work your way up.

With binary scales, each lamp has its own price: 1, 2, 4, 8 and so on. For the learning target 13, include 8, 4 and 1: 8 + 4 + 1 = 13. On your board, use an actual goal; The number 13 is just an example.

The compass calculates the turn from the previous arrow

If the beginning is ↑, the command “to the right” gives →, and the next “to the left” again ↑. After turning down, the command "right" leads to the left on the screen. Count relative to the previous direction each time.

Clicking rotates the selected arrow a quarter turn. First set the initial section, then sequentially calculate the rest - the error at the beginning is transferred to the entire series.

Sliding tiles, Latin grids and Hanoi

In tag, only the neighbor of an empty cell moves; the result is numbers in order and emptiness at the end. The Latin grid requires the numbers 1…N without repetitions in each row and column. Start with a nearly completed row and check the missing number across the column; fixed cells cannot be changed.

In Hanoi, click on the source tower, then the destination tower. A large disk cannot be placed on a smaller one. For the three disks on the left, the tutorial solution: 1→3, 1→2, 3→2, 1→3, 2→1, 2→3, 1→3. A larger set requires more moves.

After making your decision, wait for confirmation and the green arch. Closing a window does not in itself mean that the condition is met.

Completing a logic room can be one of the conditions for a separate achievement. Achievements for difficult rooms.

Frequently asked questions

Will the reset button give you an easier task?

No. It returns the original state of the same variant. The condition and solution do not change randomly after each reset.

Why don't the right colors produce finished code?

Positions matter. The hint distinguishes between the color in its place and the correct color in another place.

How to move a disk in Hanoi?

First, click the tower from which you are removing the top disk, then the destination tower. Make sure that the smaller disk is not underneath the larger one.
