Place towers on empty squares beside the road, then start a level.
How to play Tower Trail
Preview every firing range
Move the board cursor over an empty build square to see the chosen tower's colored firing circle before spending energy. Select a built tower to inspect its current range; the exact cell distance is written below the controls. Every upgrade adds reach as well as damage.
Build for the next wave
The preview shows the exact enemy mix before each level. Pulse towers fire quickly, Rail towers reach far, Frost towers slow a rush, and Cannons damage packed groups. Runners arrive at level 6, armored enemies at level 12, shielded enemies at level 20, and a boss appears every tenth level. Armor reduces non-Rail damage by 40%; Rail shots pierce it. Shields absorb whole hits, so rapid Pulse fire strips them fastest. Later waves grow larger and spawn faster; bosses resist long Frost slows.
Choose targets and rebuild
Cycle every tower through First, Strongest and Special targeting. Special prioritizes bosses, armor and active shields. Keep upgrading through rank 30, or sell between levels for 70% of everything invested. A Cannon aimed at the first enemy can catch a cluster in its blast.
Control the battle
Pause a moving level or run it at 2× speed. Leaving the tab or switching away from the game window automatically pauses an active wave. Returning does not resume it: press Resume when you are ready. Hidden time is not caught up. Progress saves on this device between levels. If the core falls, Retry restores the last checkpoint. On phones, scroll the board sideways. With a keyboard, focus the board and use arrows to inspect each square without spending energy. The status reports roads, tower level/range/target, or empty ground with cost and any energy shortfall. Press Enter or Space only when ready to place or select.

Browser storage can be blocked or cleared. A checkpoint warning means the current changes were not saved; keep playing in this tab or try another planning action after storage becomes available.
Select an existing tower, choose Move selected, then tap empty ground off the road. Moving costs no energy and keeps the tower’s upgrades and target mode. You can also use board arrows and Enter or Space; the range ring previews an empty destination. Cancel move or Escape leaves the tower unchanged. Roads, occupied squares and active or paused combat do not allow moving. Starting a level or selecting a tower type cancels the pending move.
