Aim. Fire. Destroy.
Aim, set your power and bring down enemy fortresses in a 60-stage artillery campaign.
Castle Strike is an original artillery castle battle. Your castle and an enemy fortress face off across the battlefield: drag to set your cannon's angle and power, read the wind, and lob shells over hills, walls and lava to wreck their keep before they wreck yours. The campaign runs 60 stages across six worlds — Green Valley, Desert Kingdom, Frozen Peaks, Volcanic Front, Storm Realm and the Dark Kingdom — with a boss fortress every tenth stage, five weapons that unlock as you advance, and up to three stars per stage.
You and the enemy take turns firing. On your turn, press anywhere on the battlefield and drag back — the direction of the pull sets the cannon's angle and its length sets the power — then press Fire. A few dots show how your shell leaves the cannon, but not where it lands, so it takes practice. Shells fly in a true ballistic arc and the wind (shown at the top, with direction and strength) pushes them sideways; from the second world on it can change every turn. Hitting the cannon on the roof does the most damage, towers take extra, and near misses still splash the walls. Later fortresses bring armor, regrowing shields, burning shots, twin cannons, lava, geysers and moving stone. Weapons unlock as you progress: Heavy (big blast, shorter range), Burst (splits in three), Fire (burns for three turns and melts ice armor) and Piercing (ignores armor and shields). Win to earn a star, keep at least half your castle for a second, and finish within the stage's par shots for a third. Your stars and progress are saved on this device.
Is Castle Strike free to play?
Yes — it's completely free in your browser, with no purchases, currency or ads inside the game.
How many stages are there?
60 stages in six worlds of ten, with a boss fortress on every tenth stage and a three-phase final boss.
Does the enemy aim perfectly?
No. Enemy crews misjudge the wind and their aim wobbles; they correct from their own misses as a battle goes on. Early crews miss often, later ones are sharper.
Does Castle Strike work on mobile?
Yes — drag on the battlefield to aim and tap Fire. It works in portrait on phones as well as on desktop with a mouse or keyboard.
Is my progress saved?
Yes — unlocked stages, stars and your best shot count per stage are saved in this browser. No account is needed.
