The Hackulator: a familiar Casio scientific calculator with a colour display showing the games launcher

01Overview

Same shape. Entirely new inside.

Hackulator takes an ordinary Casio scientific calculator, keeps its body and keys, and replaces the electronics with a custom board and colour display, so the calculator in your bag can also play games.

  • StatusPrototype in development. Not yet available to buy.
  • Based onAn ordinary Casio scientific calculator: same body, same keys
  • Included gamesSnake, 2048 and Tetris

Keep the keys your hands already know. Rebuild everything behind them around a colour screen.

02Inside

Four ideas, one calculator.

The concept is simple. Keep what works about the calculator and rebuild the rest around a colour screen.

Familiar keys

The recognisable calculator shape and its physical keys stay. Your hands already know the layout.

Replacement electronics

The original board comes out. A custom board designed for the Hackulator goes in its place.

Colour display

A colour screen replaces the original display, giving games and menus room to breathe.

Custom software

A purpose-built interface for launching games, changing settings and, if you choose, a personalised look.

Where the engineering stands

This is a prototype, so we're not quoting a final specification. These are the open questions as they are today.

  • TargetAn RP2040-class microcontroller with 8 MB of flash is the current design target, not a final spec.
  • OpenSourcing a colour display that fits the original housing.
  • OpenConfirming it can run on a single AAA battery.
  • OpenFinal manufacturing and assembly.

03Games

Try it. It's a calculator first.

Every Hackulator comes with Snake, 2048 and Tetris. Use the calculator below for a sum, then press Discover what's inside to open the games.

The real screen will look much nicer than this. This is just a simple web mockup of the layout. The finished Hackulator display will be sharper, smoother and far more polished.

07FAQ

Questions, answered.

Can I buy a Hackulator today?

Not yet. Hackulator is a prototype project in development. Display sourcing, running on a single AAA battery and final manufacturing are still being worked out, and the base price hasn't been set.

You can put a build together and save the summary, but nothing on this site takes orders or payments.

What comes with the base Hackulator, and what is extra?

Every Hackulator includes Snake, 2048 and Tetris. These are never charged for and can't be removed from your build.

Extras are optional: single games (£2.50 each), the Classics Pack (£5.00), Custom UI (£5.00), a name on the cover (£3.00), an icon on the cover (£4.00), or one of the two forever passes.

What does “forever” mean for the passes?

It means forever. The Gamer (£10.00) covers every current and future compatible game, including installation, updates and reinstallation of those games, with no renewal and no extra charge.

The Hacker (£20.00) does the same for all compatible software you want, games and Custom UI included. It isn't limited to the games that exist on the day you buy it.

If I uninstall a game, do I lose it?

No. Owning a game and having it installed are separate. Deleting or temporarily uninstalling something to free up space doesn't remove your ownership of it.

Which calculators is it compatible with?

Hackulator is built from an ordinary Casio scientific calculator. Not every model is suitable, so ask before planning a build if you want to use a calculator you already have.

Is this an official Casio product?

No. Hackulator is an independent modification project. It isn't made, endorsed or supported by Casio. Replacing the electronics means the device is no longer the original calculator.

Can I use it in exams or at school?

A Hackulator is a modified device, so it won't be approved for exams. Only use it where games and modified devices are allowed, and follow your school's or exam board's rules.

What does joining the waitlist mean?

Joining is free and there's no obligation to buy. It simply reserves your place in the manufacturing queue for the first small batch, in the order people joined.

When your spot comes up, we'll contact you personally with the price and details, and you decide then. Nothing is ever charged on this website, and you can leave the list any time by emailing us.

Is the Arcade Pack available?

Not yet. It will contain Block Blast, Space Invaders and a third game that hasn't been decided. It can't be chosen until all three are confirmed.
