## Description
_Numba_ is a puzzle game where you must link sequences of adjacent numbers to
make blocks disappear and new blocks fall from the top of the screen. However,
here you can match blocks in many ways — for example, you can match blocks
with the same repeated number (4-4-4, say), or you can make sequences of
numbers like 3-4-5 or 2-4-6-8. Some special blocks add variety to the mix —
blocks that blink in and out of existence, fire blocks which become solid rock
if neglected for too long, ice blocks which need to be thawed before used, and
so on.
The game has three modes: in ‘classic’ mode, you play a series of timed levels
of increasing difficulty; ‘timeless’ mode is the same as classic, but levels
do not reset, and there is no timer; finally, ‘puzzle’ mode consists of a
series of about 80 puzzles where you must eliminate all blocks (which do not
enter the screen from the top nor respawn). All modes have separate local
leaderboards.
