Grid Lock: noughts and crosses against the Spectrum. You are X: press 1–9 on the keys below to take a square (1 top left, 9 bottom right). Win a round +10, draw +5; lose one and the game ends.
Crypt Caper: explore the castle with the stick, fire with FIRE. On the title, up/down (or 1, 2, 3) picks the hero; 1–4 drop a carried item.
Apocalypso!: left/right runs, FIRE (or SPACE, M, 0) jumps. Collect all 250 Golden Tins, then reach the hatch in The Bunker.
The Gullrock Light: a text adventure. Type a command on the keys below (GET LANTERN, N, EXAMINE WELL, TALK EZRA) and press ENTER; the 0 key (⌫) rubs out. On a real keyboard just type. Tap the picture for SPACE at a “more” prompt. RAMSAVE keeps your place; HELP lists the words.
Mothfall: fly the Lamplighter through the cave with the stick (or Q A O P, or cursor keys), fire with FIRE (or SPACE, or tap the picture). Don't touch the rock. Each zone gets narrower and faster; every second zone cleared gives an extra lamp (life).
Gemquake: steer the pod with the stick (or O/P), launch the ball and fire lasers with FIRE (or SPACE, or tap the picture). On the title, left/right picks a start level once you've reached it. H holds the game, then Q quits.
Jelly Storm: move with the stick (or O/P), fire with FIRE (or SPACE, or tap the picture). The game pad opens by itself.
Save, Load, Hold: 💾 Save keeps your place in the game you're playing, on this device; 📂 Load goes back to it, even after closing the page. Hold ⏪ to wind the last 40 seconds back, then let go to carry on. ⬇ .z80 downloads a snapshot any emulator can open (inside the Claude app it comes as a .zip holding the .z80; 📼 Load opens .zip files too).
48K / 128K: Speccy starts as a 128K; tap to switch machine (the game restarts, and your choice is remembered). Every game here plays AY music on the 128K — title songs, in-game songs that change with the zone, wave, level or castle floor, and jingles — and the original beeper sound on the 48K. ⏱ Real gives true Spectrum speed (memory contention); turn it off for the old, slightly faster timing.
Controllers: plug in or pair a game controller and press a button — the stick or d-pad moves, A/X fire, B/Y press the blue B key, Start presses ENTER. It follows the pad's mode (Kempston or a key layout).
Game pad: Kempston mode works with any game that offers a Kempston joystick in its menu (Atic Atac: press 2). The blue B button presses one keyboard key of your choice — for Atic Atac leave it on Z, which picks up and drops items. For keyboard-only games pick a key layout, or Custom to choose each key.
My tapes: every tape or snapshot you load is kept in this browser on this device only, so next time it's one tap. Tap ✕ to remove one.
Keys: tap the on-screen keys, tap the picture for SPACE, or use a real keyboard (Shift = CAPS SHIFT, Ctrl/Alt = SYMBOL SHIFT). CAPS and SYM are sticky on touch: tap once, then tap the next key.
Your own files: 📼 Load opens tapes (.TAP, .TZX, .PZX, .CSW, .BLK), snapshots (.Z80, .SNA, .SZX), screens (.SCR) and ROMs (.ROM), also inside a .ZIP or .GZ; any file can be picked and Speccy works out what it is. Disk images (.DSK, .TRD and other +3 / Beta / Microdrive files) need hardware Speccy doesn't emulate. Tapes load through the Sinclair ROM, which is built in: Speccy types LOAD "" (or picks Tape Loader on the 128K) for you, and the game starts a few seconds later. Standard tape blocks load instantly; turbo and custom loaders in .TZX files play at high speed. If one of your tapes won't run on the 128K, switch to the 48K. The built-in games use quick start (no ROM) so they begin at once. You can add your own ROM file instead (16 KB 48.rom for the 48K, 32 KB 128.rom for the 128K) and Speccy uses it for everything.
