The other half of the capsule

Clearing a virus can solve one problem while the remaining half of a capsule falls into another. Good play means keeping access to buried colours, not simply making the nearest match. The bottle gradually becomes a record of compromises made under time pressure. Against another player, chain reactions turn that private tidying exercise into an attack, so preparing a delayed clear can be worth more than a quick one.

Start at a low speed and learn what happens when only half a capsule disappears. Keep paths down to the lowest viruses. In two-player games, choose settings that let both players make deliberate decisions before raising the pace.

Set your own pace

The 1990 Famicom game makes room in the console’s library for repeatable competitive sessions. Virus level and falling speed are separate settings, letting players change the density of the puzzle without immediately increasing the demand on their hands. The cartridge edition is the subject here; the contemporaneous handheld version has a separate presentation.

Why we chose it for NES / Famicom

A two-player puzzle game broadens the journey beyond platforming. Low speed leaves time to see how capsule halves set up later chains.
