Numberland Blast is a match-3 game mixed with number sequences. You connect 3 or more consecutive numbers to clear the blocks. You can link any blocks that are immediately higher or lower in value to the previous one. For example, you can match 1-2-3, and also 3-2-1.
In addition, you do not have to go a single direction: you can change whether you go higher or lower while you are linking blocks! For example, you can link 1-2-3-2-1.
Each level will have a certain goal that is required for you to meet in order to clear the level. This may be achieving a certain score, clearing certain blocks, or defeating a boss!
