About

RyanRun

Read full description

RyanRun is a match puzzle game with real-time tower defense battles. Match cube patterns to rescue hostages while defending against advancing monsters. The beast god corps have taken Prince Ryan's kingdom hostage. Talents like you are the last line of defense. Swipe, match, and fight your way through waves of monsters before time, or moves, run out. Match to save lives Every tile is a six-sided cube. Swipe left, right, up, or down to rotate each face and line up matching patterns. Match the required number of identical faces, then double-tap to clear them. Every cube you clear moves a hostage one step closer to freedom, but it also brings danger one step closer too. Race the monsters to the finish line As hostages march toward safety, beast god monsters advance from the opposite direction. Let a single monster reach the finish line, and every hostage on the board is lost. Use your gold to recruit soldiers and heavy arms, including snipers, tanks, and more, and station them at the front line to hold back the horde. Power up or panic - Boom instantly wipes out monsters on the board. - Twist pushes every monster back to the top, buying precious time. - The power-up restores hostage energy to full before they run out of strength. - Drag and drop lets you reposition hostages within a row to dodge incoming threats. Build your defense Earn gold from every match and hostage rescued. Spend it wisely on soldiers, snipers, tanks, and other arms, each with unique range, reload speed, and cost. Upgrade your arsenal as monster waves get tougher across each level. Become the hero of a new era Every hostage saved is a life reclaimed. Every mission completed brings the kingdom closer to freedom. Do you have what it takes to out-match, out-build, and outlast the beast god corps? Swipe, match, defend, rescue. Freedom starts with you. RyanRun combines classic match-style puzzle mechanics with real-time tower defense strategy.
