Gravity flip for beginners comes down to one rule: read the next corridor column, then choose Advance to keep the runner on its current floor or ceiling or Flip + Advance to switch sides before entering that column. The Gravity Flip Game turns that choice into a deterministic, no-timer route through five levels. The runner starts on the floor with downward gravity in column one, while every later column contains one fixed obstacle on either the floor or the ceiling. Nothing moves unless you issue a command, so you can inspect the board, pause, and make the decision without racing a clock. A safe action advances the runner and adds the chosen side to its visible path. A blocked choice produces a real collision rather than a decorative animation: the runner stays put, and position, side, gravity, score, and path remain unchanged. Complete every obstacle column in all five levels to earn exactly 1,000 points, with 200 points awarded for each level.
Read the Corridor Like a Two-Lane Board
Here, “gravity” names a deterministic floor-or-ceiling mechanic, not a simulation of acceleration, mass, velocity, hardware sensors, orbital motion, or a measured physical system. The runner can occupy only the floor or the ceiling. The text status reports its current side, whether gravity points up or down, and the exact column reached. The board also renders the completed side path as dots, allowing you to check how earlier decisions connect to the current position.
Every level uses one persistent fixed corridor. Column one is a clear starting position, and each later column contains one obstacle on either the floor or the ceiling. Obstacles do not move, randomize, or disappear after a failed attempt. Your task is not to react to an incoming hazard; it is to read the next visible column before committing to one of two deliberate commands.
| Control | What it does | If the destination side is blocked |
|---|---|---|
| Advance | Keeps the runner on its current floor or ceiling side and enters the next fixed column. | The move collides. Position, side, gravity, score, and path remain unchanged. |
| Flip + Advance | Reverses gravity, transfers the runner to the opposite side, and then enters the next fixed column. | The entire move fails atomically. There is no partial flip, partial advance, or path change. |
Make a Safe Move in Every Column
- Check the opening state. On a fresh or restarted session, confirm that the runner is on the floor, gravity points down, and progress starts at column one. The initial path contains one floor node, and the score is zero.
- Read the destination column. Find the column immediately after the runner’s current position and note whether its single obstacle occupies the floor or the ceiling. You only need to decide for this next column.
- Compare the obstacle with the current side. If the obstacle is on the side opposite the runner, choose Advance because staying on the current side avoids it. If the obstacle is on the runner’s current side, choose Flip + Advance so the runner enters the clear opposite side.
- Commit to one complete command. Select Advance or Flip + Advance rather than treating them as separate actions. With the game area focused, press A or Right Arrow to advance and F to flip and advance. The native buttons perform the same actions.
- Check the feedback. After a safe action, the runner advances one fixed column, the status shows the new side, gravity direction, and column number, and the path extends with the side used. If a collision occurs, none of those values change.
- Clear the final obstacle column. Clearing it awards exactly 200 points. The next level then begins on the floor with downward gravity at column one and a fresh one-node path.
- Repeat the routine through level five. Read each new corridor from column one, make one deliberate decision per destination column, and complete all five levels for exactly 1,000 points.
Recover From a Collision Without Guessing
A collision is a complete failed move rather than a partial transition. If the destination contains an obstacle on the runner’s chosen side, Advance does not move the runner. Likewise, a failed Flip + Advance does not leave the runner upside down: the flip and advance are evaluated together, and a blocked move leaves side, gravity, position, score, and path unchanged.
The failure system records a signature made up of the level, current segment, and normalized action. Normalization accepts the visible action names regardless of surrounding spaces or letter case, and the plus-sign form of Flip + Advance matches its internal hyphenated form. Repeating the same failed action at the same segment is deduplicated, so it does not consume the second failure. After one collision, take the safe action for that column: advance if the obstacle is on the opposite side, or flip and advance if it is on the current side.
A later collision with a different failure signature creates a second failure and deadlocks the runner. Once deadlocked, both controls remain frozen until Restart is used. Restart reconstructs the exact first-level opening state: floor side, downward gravity, column one, an empty failure set, zero score, and a one-node floor path. The fixed obstacle also remains visible after a failed attempt; Restart resets the session rather than removing the block.
Know the Five-Level Score Path
The levels differ in length, but they use the same fixed columns and the same two controls. The obstacle counts and completion awards are defined as follows.
| Level | Fixed obstacle columns | Points for clearing the final column |
|---|---|---|
| 1 | 4 | 200 |
| 2 | 4 | 200 |
| 3 | 5 | 200 |
| 4 | 5 | 200 |
| 5 | 6 | 200 |
Each level opens with the runner on the floor, downward gravity, column one, and a fresh path. Clearing the final obstacle column awards the level’s 200 points, and completing all five levels produces exactly 1,000. Because the corridor layouts and decisions are deterministic, the same sequence of choices produces the same result on every run. There is no background timer to push the runner forward while you think.
Choose Keyboard, Touch, or Assistive Exploration
You can use the native buttons or the keyboard. The buttons expose both actions directly, provide a minimum 44-pixel interaction height for touch, and support standard Enter or Space activation. Keyboard handling is scoped to the focusable game area rather than a global window listener: press A or Right Arrow to advance, and press F to flip and advance. Moving focus or exploring the interface with a screen reader cannot create a delayed automatic step because the game has no timer.
The corridor remains fully visible during play. Each column exposes its obstacle side, the current runner side when present, and the completed path side after that column has been traversed. The game does not add a safe-action label, solution sequence, correct index, correctness class, answer data attribute, or hidden route. You are reading the playable geometry rather than receiving an answer annotation.
The widest level contains seven columns and uses a minimum-zero grid, compact symbols, wrapping text, and an overflow guard to remain contained on a 390-pixel phone. The game runs locally in the browser as a client-side game. Decisions, paths, collisions, and scores are not uploaded for processing, and no account is required. Advance and Flip + Advance are the only commands that can change an active, non-deadlocked session; Restart resets the session, and both action commands are no-ops after completion. Unknown commands, empty input, and non-string values are atomic no-ops.
Use a Quick Pre-Move Check
- Current: Read the runner’s floor or ceiling side and up or down gravity from the status.
- Next: Identify the obstacle side in the next visible column.
- Command: Choose Advance for an obstacle on the opposite side or Flip + Advance for an obstacle on the current side.
- Result: Confirm that the column number and path advanced after a safe move.
This check removes the guesswork without requiring speed. If the first decision collides, the board still shows the same position and path, so you can apply the safe action at that segment. Repeating an identical failed decision there does not consume another failure, but making a different failed decision creates the second signature and deadlocks the level until Restart.
