calculator games:

Calculator gaming is a form of gaming in which games are played on programmable calculators, especially graphing calculators.

In 1980, Casio's MG-880 pocket calculator had a built-in "Invaders" game (essentially a downscaled Space Invaders clone),[14] released in the Summer of that year.[15] Another early example is the type-in program Darth Vader's Force Battle for the TI-59, published in BYTE in October 1980.[16] The magazine also published a version of Hunt the Wumpus for the HP-41C.[17] Few other games exist for the earliest of programmable calculators (including the Hewlett-Packard 9100A, one of the first scientific calculators), such as the long-popular Lunar Lander game often used as an early programming exercise. however, limited program address space and lack of easy program storage made calculator gaming a rarity even as programmables became cheap and relatively easy to obtain. it was not until the early 1990s when graphing calculators became more powerful and cheap enough to be common among high school students for use in mathematics. T new graphing calculators, with the ability to transfer files to one another and from a computer for backup, cold double s game consoles.

calculators such as HP-48 and TI-82 could be programmed in proprietary programming languages such as RPL programming language or TI-BASIC directly on the calculator; programs could also be written in assembly language or (less often) C on a desktop computer and transferred to the calculator. S Calculators Baseium More Powerful and Memory Sysges Increase, Games Increase in Complexity.by the 1990s, programmable calculators were able to run implementations by hobbyists of games such as Lemmings and Doom (Lemmings for HP-48 was released in 1993;[18] Doom for HP-48 was created in 1995[19]). Some games such as Dope Wars caused controversy when students played them in school.

the look and feel of these games on an HP-48 class calculator, due to the lack of dedicated audio and video circuitry providing hardware acceleration, can at most be compared to the one offered by 8-bit handheld consoles such as the early Game Boy or the Gameking (low resolution, monochrome or(grayscale graphics),

Games continue to be programmed on graphing calculators with increasing complexity. A wave of games appeared after the release of the TI-83 Plus/TI-84 Plus series, among TI's first graphing calculators to natively support assembly. TI-BASIC programming also rose in popularity after the release of third-party libraries. assembly remained the language of choice for these calculators, which run on a Zilog Z80 processor, although some assembly implements have been created to ease the difficulty of learning assembly language. for those running on a Motorola 68000 processor (like the TI-89), C programming (possible using TIGCC) has begun to displace assembly.

Because they are easy to program without outside tools, calculator games have survived despite the proliferation of mobile devices such as mobile phones and PDAs.
