NULLGRID

A block-breaking puzzle where you pilot a rescue bot and take the grid back from rogue AI. Playable concept build.

Level map

10,000 levels in 500 sections

Every section is 20 levels with its own scene, colors and featured twist. You travel between sections by sliding to the next scene, teleporting or warp-jumping. Level 20 of each section is a gate guarded by an Overmind, and every section has a star chest to earn.

What keeps players coming back

Unlock timeline

Something new to reach, all the way to level 10,000

New special blocks, power-ups, enemies, hazards, pilots and section twists arrive gradually, and rank titles keep coming deep into the thousands. Ticked rows are unlocked.

    How a level plays

    One turn on the grid

    1. Read the mission

      Every level has 2–3 goals: score points, destroy a number of bots, and from level 2 a third goal such as clearing one color, repairing corrupted blocks, or making big clusters. You need all of them before your moves run out.

    2. Swap and match

      Swap two neighbouring blocks to line up 3 or more of a kind. Matching 4 in a row, an L or T shape, 5 in a row or a 2×2 square builds a special block. Swap a special with any neighbour to fire it, or swap two specials together for a special combo. Cascades score extra.

    3. Fight the bots

      The bot faces in the grid are rogue AIs. Make matches next to one to damage it. The red dots on each bot count down to its next strike, when it corrupts a neighbouring block. More bots drop in until you hit the quota.

    4. Finish strong

      When every goal is done, each leftover move fires a bonus laser. Your final score earns 1–3 stars on the level map. Each level adds +0.1 difficulty.

    Characters

    Rescue pilots

    Your pilot is you on the grid. They sit in the dock under the board, fire every power-up you use, talk you through the mission, and charge Overdrive: every 30 blocks you match, they load a free charge of their signature power-up. Each pilot also starts every level with +1 of that power-up. In this demo every pilot is unlocked; pick one to swap in.

    Rogue AI

    The robot faces inside the grid are the enemy: rogue AIs that have taken over the grid. Each one has an HP bar and a row of red dots that count down to its next strike, when it corrupts a neighbouring block. Clear blocks next to a bot to damage it. Destroying bots is a goal on every level, and reinforcements drop in from the top until you reach the quota.

    Grid blocks

    Tech instead of candy

    Every block is a piece of AI hardware with its own outline, so you can tell them apart by shape as well as color. Holiday themes change the colors but never the shapes.

    Special blocks and mechanics

    Special combos

    Swap two special blocks into each other. They spiral together, fuse, and fire a combo of their own. All 10 pairs are different.

    Power-ups

    Tools to destroy and change blocks

    Power-ups can be combined into 10 unique combos and upgraded to higher rarity. You get 1 charge of every unlocked power-up at the start of each level. Your pilot's Overdrive, supply crates and rewarded ads give more. Using a power-up never costs a move, and every power-up sets off any special block it hits.

    Combos

    Tap one power-up, then tap a different one to arm a combo, then tap the grid. Every pair has its own effect, and a combo uses one charge of each. If either power-up is Epic or better, the combo deals 1 extra damage.

    Workshop: power-up rarity

    Spend coins to raise each power-up from Common to Rare, Epic and Legendary. Every tier hits harder or reaches further, and the upgrade is permanent. Pro starts every power-up at Rare. You have 0 coins.

    Side quests & events

    Weekly challenges, side quests and holidays

    Reasons to come back every week. Side quests stock you up on power-ups, the weekly challenge pays out in three tiers, and every holiday brings a themed event with an avatar you keep forever. Progress here is real: play the demo above and watch it fill in.

        Supply Run

        Power-up crates are scattered across the grid. Clear blocks next to a crate to crack it open and keep the power-up inside. Open 5 crates in 16 moves. Bots still guard the grid.

        More side quests for the full game

        • Bot Hunt: destroy every bot within 10 moves. Rewards a rare power-up.
        • Rescue Mission: free a trapped pilot buried under steel blocks to unlock them early.
        • Blackout: the grid goes dark and only blocks near your last clear are visible.
        • Vault Break: a 60-second speed round for a pile of coins.

        Holiday events and avatar rewards

        Each holiday runs as a limited-time event with its own block theme, a twist on the rules and three reward tiers. Tier 3 is an avatar item any pilot can wear. All seven are playable now: clear 3 levels in that theme to earn the avatar.

        Difficulty curve

        +0.1 difficulty every level

        Difficulty is 1.0 + 0.1 × (level − 1), so level 10,000 shows 1,000.9×. The rules it controls (bots, HP, score targets, moves, goal sizes) climb steeply over the first few hundred levels and then level off, so every level stays winnable. After that, variety comes from each section's scene and featured twist. The first levels of each section are slightly easier, as a breather after the gate. These rows come from the same formulas the game uses.

        Late levels are tuned to lean on power-ups and pilot upgrades. Expect to rebalance the target curve after playtesting.
