Seven Surge

SEVEN SURGE is a portrait one-finger number puzzle set on a neon grid under a violet night sky. Your guide is Volt, a cheerful little spark, and every stage is a race against the charge meter: light every beacon on the board before your charges run out.
Control is a single drag. Put your finger on a tile and draw through its neighbours, up, down, left or right, while a bubble above the arc shows the running sum. Slide back onto the previous tile to undo a step. Let go at exactly 7 and the arc surges; let go at any other sum and it simply fades, costing nothing. Sound, music and vibration can each be switched off in Settings.
The board holds tiles numbered 1 to 6: six by seven on the first three stages, six by eight after that. Every surge clears its tiles, the columns drop and fresh tiles fall in from the top. Glowing beacons sit on fixed cells, and an arc that passes over a beacon lights it. The first stage asks for 4 beacons with 11 charges, and every stage after it adds more of both, up to 19 beacons and 23 charges on stage 30.
Each surge spends one charge. Run out with beacons still dark and the stage stays unlit: try again right away, the beacons keep their places and the tiles come out fresh. Finish with at least 35% of your charges left for three stars, with 15% for two.
Long arcs pay off. A two-tile arc scores 70 points and every extra tile doubles it, so 1+1+2+3 is worth four times as much as 3+4. Draw four tiles or more and the arc overloads: it also lights every beacon on a cell right next to it. Stuck? A Pulse shakes up all the tiles without spending a charge, and after six quiet seconds the best arc starts to glow as a hint.
