How to Play Gloop Siege
Your goal is simple: pop every gloop hiding in the fort before you run out of birds. Drag the loaded bird near the slingshot, pull back to aim — a dotted arc previews your trajectory — then release to fire, and tap the screen mid-flight to trigger that bird's special ability. Each bird type has a strength: yellow shreds wood when dashing, blue splits into three to shatter glass, and black detonates to crack stone. Strategy tip: don't shoot the gloops directly — knock out the structure's supports instead and let the collapse do the crushing, since falling blocks cause chain reactions that clear whole towers (and extra blocks mean more points).
