Woodoo is a cozy wood-block puzzle stitched together with a little folk-magic charm โ and now there is something new to do every single day. NEW: DAILY CHALLENGE One puzzle, one board, and everyone in the world plays the very same one. Soap bubbles are scattered across the grid: pop them all by clearing the lines they sit on, and beat the clock for a bigger reward. Finish and your day is stamped on the calendar, so come back tomorrow and keep the streak alive. Did a day get away from you? Revive and carry on right where you left off. NEW: CHARM COLLECTION EVENTS Every month brings a new themed journey. Charms ride along inside your wooden pieces during normal games โ clear the line that holds one and it is yours to keep. Fill the album one stop at a time. โข August โ Mend the Doll: gather thread and patch charms to stitch Woo back together, from Loose Seams to Torn Sleeve, Frayed Hem, Patched Heart and finally Good as New. โข September โ Bone Harvest: dig up bone after bone, from First Dig all the way to a Full Skeleton. Every stop you complete pops open a chest of buttons, and finishing the whole album pays a generous bonus. SIMPLE TO LEARN Drag the carved wooden blocks onto the 8x8 board. Fill a full row or column to clear it. No timer, no pressure โ play at your own pace. CAST THE MAGIC Chain your clears back-to-back to set the board on fire, trigger combos, and empty the whole grid for a satisfying All Clear.
