Pushover
aka Push-Over
Pushover turns a bag of lost potato chips and a set of unstable dominoes into one of the most clever, agonizing puzzle designs on DOS.
Rearranging dominoes under a cruel clock in Pushover
Red Rat Software took a simple idea and made it surprisingly ruthless. You play G.I. Ant, a large soldier ant navigating a side-view maze of ledges and ladders to recover snack packets. The objective for every level relies on setting off a single, uninterrupted chain reaction.
You can pick up and move almost every domino block on the board, but you only get one shove. The regular yellow-and-red patterns will fall in sequence, but success requires triggering the designated three-striped Exit block last. If that trigger falls too early, or if any standard domino is left standing, the exit door stays locked and you fail.
The variety of special blocks keeps the basic mechanic from getting repetitive. You have to account for several distinct behaviors across the board:
- Stoppers that halt any momentum cold.
- Tumblers that roll off edges and keep going across flat floors.
- Ascenders that float straight up until they hit a ceiling.
- Exploding blocks that blast holes through platforms to let falling tiles pass.
- Splitters and delay blocks that divide the line or buy precious seconds.
What makes the design so demanding is that G.I. Ant is fragile. Dropping from a ledge that is slightly too high causes you to splatter instantly. Leaving a single pile of rubble in front of a pathway can lock the stage. Worst of all, the tight time limit forces you to sprint toward the open door the second you knock the first tile down.
The design brilliance of Red Rat Software and Ocean Software
The team at Red Rat Software, led by concept creator Charles Partington, engineered 100 levels spanning nine visual themes. Designers Helen Elcock, Harry Nadler, Avril Rigby, Don Rigby, and Chris Waterworth constructed these puzzles using a custom internal editor. Ocean Software published the title in 1992 with cross-promotional snack branding in the UK, though international releases replaced the chips with cash dropped by Captain Rat.
At the time, gaming magazines drew immediate comparisons to Lemmings. *Computer Gaming World* highlighted its addictive puzzle philosophy, while *ST Format* noted that planning mattered far more than raw reflexes. The game relied on deliberate spatial logic rather than quick trigger fingers, which made the strict countdown timer feel like an odd contrast to the thoughtful core design.
On PC, the presentation held up well thanks to colorful backgrounds and expressive character animations. G.I. Ant balances nervously on ledges or covers his ears when explosives go off. The audio side scored high marks too, featuring dynamic soundtracks from Jonathan Dunn, Dean Evans, and Keith Tinman that sounded punchy through an AdLib or Sound Blaster card.
Tight timers and touchy controls make for high frustration
For all its clever logic, the mechanics suffer from a few mechanical flaws. Placing dominoes requires exact alignment, and the keyboard controls can feel slightly sluggish when you try to turn around quickly. Accidental drops or misplaced tiles happen often, forcing you to use the built-in stage undo feature or retype level passwords.
The extreme difficulty spikes later in the run turn trial-and-error into a test of patience. Figuring out how gravity-reversing blocks interact with splitters is satisfying, but executing the solution under a five-second exit window is not. Reviewers noted that younger players would likely bounce off the strict execution long before reaching the final world.

This classic puzzle title holds up because its core mechanics are clear, punishing, and immensely rewarding to solve. The satisfaction of watching a massive domino chain execute perfectly after twenty failed attempts remains unbeatable.
