Koi Pond
Feed the whole pond — once each. Remember who you’ve fed.
What this trains
Selective attention, multiple-object tracking, and working memory — holding which fish you’ve already fed as they move and mix.
This game trains the underlying capacity your game leans on. Direct transfer from screen to pitch is limited and debated — we don’t claim it makes you a better player. We claim it trains the capacity, scores you honestly, and is worth your ten minutes.
How to play
Feed every fish once by tapping or clicking it. Nothing marks who needs feeding — that’s the point.
After each feed a feed timer counts down; you can’t feed again until it’s full. Use the wait to keep track of who you’ve fed (their colour helps).
Don’t feed the same fish twice — re-feeding is the mistake. Clear the whole pond and it grows by a fish.
