Where 9918 fits
Why 9918 is special
Sprites in hardware meant a slow processor could still move objects smoothly, which is what made playable games possible on modest machines.

Read as powers of two: 8,192 + 1,024 + 512 + 128 + 32 + 16 + 8 + 4 + 2 = 9,918.
In historical numeral systems
Egyptian
9 lotuses, 9 coils of rope, 1 hobble, 8 strokes
9 × 1,000 + 9 × 100 + 1 × 10 + 8 × 1 = 9,918. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.
