About this game
■ What's this game? This is a competitive falling-block puzzle game based on the theme of Blackjack. Match numbered blocks to clear lines and send garbage blocks to your opponent's field. Master the "STOCK" and "JACK" systems to bury your enemy under a mountain of blocks! ■ Overview This game was created using the “pico-8” game engine and is available for free on the “lexaloffle” forum. The Steam version includes all the features of the free version, plus the following additions! Music Room You can listen to the game's tracks. An original soundtrack featuring rearranged versions of the game's music Saved in the “NumbakoSoundTrack” folder within the installation directory! Supports Online Multiplayer PvP via "Remote Play Together"! You can play against your friends! ■ Rules Left/Right: Move the drop line. X Button (X key): Drop a box into the selected line. O Button (Z key): Cycle through the boxes in your deck. When a horizontal line is filled... JACK (Total = 21) = 21 JACKPOT! Sends a massive amount of blocks to your opponent! BUST (Total > 21) = 38 The line clears along with any "STOCK" lines. Let's send blocks to your opponent! STOCK (Total < 21) = 18 The line enters a ready-to-clear state. It's the “charge” state that boosts attack power! not STOCK (Total < 10) = 0 If a line's total is less than 10, it becomes "not STOCK... These lines can ONLY be cleared with a "JACK." Deal with them before you run out of space! ■ 2-Player Controls Keyboard controls for Player 2 are as follows: “A” and “D”: Left and Right arrow keys “Q”: X button “W”: O button While I have tested controller controls for Player 2 in our development environment, due to Steam's terms of service, we recommend using a keyboard only. Please note that the Pause button does not work to pause the game for Player 2.
