Waveflip BPD plays on a mountain lake of glowing ripples that must all fade out. A short tap flips only the chosen wave, while a held press also flips orthogonal neighbors, giving two tools in one gesture. Wavy staggered rows make the board feel like water rather than a flat grid of boxes. Some later ripples stay permanently off, narrowing legal targets and changing how chains resolve. Ripple animations and cool lake colors reinforce the surface theme during each attempt. Stay inside the move budget while clearing every free glow. Settle the lake across three expanding ripple charts.
