Whack‑a‑mole, gone fishing.
Every bobber has a key (or tap a spot).Tap a bobber to strike. Ripples mean a fish is sniffing; when the bobber plunges, strike its keytap it. Striking during the ripples scares it off, an empty spot splashes −2, and the old boot isn't worth hooking (−5). Five catches in a row double your points; ten triple them. As in typing, a tag shows what to type: a small letter or a number is its key alone, and a gold tag’s capital or symbol (Q ! %…) is Shift + its key.
