OVERFLOW

Place. Merge. BANK—or take one more turn.

OVERFLOW is a quick number-merging puzzle. Place the NEXT number in an empty cell; matching neighbors merge into a bigger number. You have five seconds to choose each move. When the clock runs out, AUTO DROP places the number in a random empty cell and play continues.

After a merge, you can BANK your unconfirmed points. Keep going to build a COMBO: three consecutive moves with merges trigger FEVER, giving you 4 or 8 as NEXT for three moves. Making 16 clears one of the smallest tiles; making 32 or higher clears up to two. Your third BANK is FINAL BANK and ends the run safely. If the board fills, you OVERFLOW and keep only BANKED points.

How to play

• Tap or click an empty square to place NEXT.
• Match neighboring equal numbers to merge. A merge opens a brief BANK opportunity.
• Decide whether to BANK your points or keep the COMBO and press on.
• At zero seconds, AUTO DROP chooses an empty square for you. A full board ends the run.
• The third BANK is FINAL BANK: it secures the score and ends the run.
