Tap anywhere in a column

Rules

Drop the next token. Tap a column, or press 1–4.
Match symbols to clear pads. Pairs connect across or down. Diagonals need three. A line of three can hook one more off either end. Falling pieces chain.
Keep a column open. Full columns block the next token.
One top clear per column. The ↓1 marker shows when a modifier or swap reaches the top. Match it from above once; a swap at the top takes any token and pays double. Used markers never come back.
Swap tiles recycle. Tap the white recycling tile to blink it, then tap any tile to move it there. An X is removed outright. Tap again to cancel.
Every four changes locks a drum. Each clear after the first changes the current drum. Locked drums keep playing.
Drop your locked drums. Clear beneath them for +500 each.
Play each token before the count runs out. Time up drops an X into your last column.

Four stages, seven levels each. Wilds arrive at 1.5, top clears at 2.4, swaps at 2.5, each dealt 1 in 30. Stage 3 starts with loop pads that count toward the bar. Stage 4 starts with Xs: a Wild landing on one clears it, a swap removes one.

The symbols

Double: Add in-between pulses.
Expression: Strong anchors, softer supporting hits.
Add: Add supporting hits.
Subtract: Strip back or soften the groove.
Special: Match two to change the current drum.
Wild: Matches any ordinary symbol, taking the largest clear. Clears any X it lands on. A clear of three or more with a Wild pays triple.
Swap: Tap to blink, then tap another tile. Swap disappears; tiles above fall.

Scoring
Match or bonus	Points
Initial pair	+25
Extra pair in a chain	+100
Snake or group Three or more of a kind	+100 per token
Lock a drum Extra for each drum	+25
Drop a saved drum Extra, once per drum per move	+500
Drop a token Each ordinary token that falls when you clear beneath it	+50
No match	0
Chain reaction The move's points, times the number of clears	×2, ×3…

+300+500+100= 900 ×2

Every match in a chain scores, then the chain multiplies the move: two clears double its points, three triple them. A snake counts each cleared token once. Newly locked drums earn the lock bonus; their fall bonus starts on later moves.
