3 Strategic Gameplay Modes
Designed for diverse player styles, ranging from calm spatial problem solving to intense high-stakes time pressure:
Classic Endless
No timers, no stress. Plan ahead, clear multiple horizontal and vertical lines simultaneously, and trigger escalating pentatonic chord combos to achieve the highest global score.
90-Second Blitz
High-octane arcade sprint. Score points as fast as possible before the clock expires. Every line clear adds bonus seconds and activates a 2x frenzy multiplier.
Bomb Challenge
Tactical emergency mode. Danger bombs spawn on the grid with active move countdowns. Strategically clear the rows containing the bombs before they detonate.
Tactical In-Game Boosters
Unlockable through gameplay achievements, rewarded AdMob videos, or the Jewel Vault:
Hammer Strike
Smash any single obstructing block on the grid to create immediate clearance for large 3x3 blocks.
Dock Shuffle
Reroll all three pieces currently sitting in your dock when no viable moves remain.
Laser Beam
Vaporize an entire row or column instantly, triggering cascades and massive streak bonuses.
