About Tower Defense
Tower Defense is a grid-based defense game with four tower roles and direct per-tower upgrades. Wave rewards add a second progression layer by letting one global tactical perk persist for the rest of the run.
How to Play Tower Defense
1Choose one of the four tower types and tap an empty grass tile to place it.
2Tap a placed tower to inspect its range and upgrade cost.
3Start the next wave and let towers attack enemies moving along the fixed path.
4After clearing the wave, choose one tactical reward before continuing.
Tower Defense Rules
- Towers cannot be placed on the enemy road or on an occupied tile.
- Direct upgrades increase a selected tower's level and combat stats.
- The base starts with 20 HP and the run ends when enemies reduce it to zero.
Tower Defense Economy
| Action | Gold / Effect | How it works |
|---|---|---|
| Basic tower | 25 gold | 10 damage, 2.5-cell range, 30-frame fire rate. |
| Sniper tower | 50 gold | 40 damage and 4.5-cell range, but a slower 80-frame fire rate. |
| Splash tower | 75 gold | 15 direct damage plus half damage inside a 1.2-cell splash radius. |
| Slow tower | 40 gold | 5 damage and applies a temporary slow that reduces enemy movement to 40% speed. |
Tower Defense Game Mechanics
Objective
Place four tower types on grass tiles and stop enemies from following the fixed path to your base.
Round End
Each enemy that reaches the end of the path removes 1 HP. The run ends when HP reaches zero; clicking the board after Game Over resets the run.
- Four tower types can be placed on grass: Archer, Watch, Mortar and Frost.
- Selecting a placed tower shows its range and enables direct gold upgrades that increase its level, damage and range.
- After each cleared wave, choose one of three permanent run upgrades such as global damage, fire rate, range, reward gold or an immediate war chest.
- Every fourth wave includes a tougher boss enemy.
- Wave, kills, towers, gold and HP exist only for the active run; this implementation does not save progress to localStorage.
Tips & Strategies
- Upgrade towers covering multiple path turns before spending gold on weak edge positions.
- Frost plus Mortar is useful because slowing keeps grouped enemies inside splash range longer.
