Grid Defense
Strategy
Free · In‑App Purchases · Designed for iPad
GRID DEFENSE is a fast, hand-tuned tower defense game about one simple job: hold the line.
Six towers. Seven breeds of creep. One winding path. Place your defenses, upgrade under pressure, and stop everything the grid throws at you across 25 escalating waves — then push into endless mode.

THE FULL GAME UNLOCKS
• All 25 waves + endless mode
• A second battlefield — The Quarry, where terrain fights back. Golems terraform the ground as they march, ore pockets pay out gold when cracked, and a keystone wall splits the map — hold it or watch the shortcut open
• Tower-smashing GOLEMS — armored bruisers that stop to wreck your towers
• WARDENS that raise energy shields — burst them before they recharge
• A deployable DWARF hero — a roaming gunner only the wasps can touch, who levels up to repair wrecked towers and mine ore for gold
• Bosses and the final victory stand
• The global online leaderboard — submit your score and claim your rank
SIX TOWERS, EVERY ONE USEFUL
Gunner, Cannon, Frost, Venom, Tesla, Sniper — each with upgrades and a role. Freeze a swarm, chain-zap a cluster, poison the tanks, or snipe through armor. There's no single right build.
AN ORIGINAL SCORE
A title theme by IVEM BEATS plays you in, and every tower fires its own sound — know what's shooting without looking.
BUILT FOR TOUCH
Designed for the phone from the ground up — tap to build, tap to upgrade, pinch and pan the battlefield. The board fills your screen edge to edge. Landscape, smooth, and playable offline.
No ads. No subscriptions. No login. Just you, the grid, and the line you have to hold.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Three releases in one update. The HUD now reads clearly at every size, and a
handful of long-standing annoyances are gone.
READS PROPERLY NOW
• The next-wave preview describes the map you are actually playing. It used to
compute the Foundry's wave on every map, so on the Quarry the early golem
never showed up in the one line you read before deciding what to build.
• Text stays inside the thing it belongs to. A maxed tower's two specialisation
choices no longer overlap each other or spill across SELL, the next-wave line
stays in its panel, and a message about a tower on the outer column no longer
paints off the edge of the board.
• The tower info panel no longer runs out of its own box.
• "rng" is now "range". It always meant the tower's reach.
FIXED
• A run that ends at double speed ends once. Losing your last life on 2x could
squeeze in one more simulated moment - enough to bank a wave you did not
survive, and occasionally to flash VICTORY over the game-over screen.
• Idle tower effects no longer run faster on a 120Hz screen. They are paced by
time now instead of by frames, so a ProMotion iPhone shows them at the speed
they were designed for.
• Purchases that are pending, cancelled or failed are reported honestly instead
of silently doing nothing.
NEW
• A frame-rate readout you can switch on in Settings. It costs nothing to leave
running and turns "it feels slow" into a number worth reporting.
• The dwarf crew moved into the bottom bar. The deploy and upgrade chips used to
float over the corner of the battlefield; they now sit with the rest of your
controls, between the tower buttons and SEND WAVE.
