Open any game from the home page and you can start straight away; each game explains its own controls the first time you play. This page covers the ideas they share.
The games in a sentence
Vaults: crack logic locks (each gives you clues; work out the code), earn relics, and use them in battles and the Gauntlet.
Rune Slide: move runes around the board to make matches and clear the stage within your move limit. Tile Swap mode lets you swap two runes instead.
Firewall: drag your turret left and right to shoot down bugs and malware, grab good pickups, dodge bad ones, and choose an upgrade after every wave.
Spell Hive: link neighbouring letters to spell words; longer words and the centre letter score more.
Spark Stack: tap to drop each block; line it up exactly to keep the tower wide.
Spark Boxes: take turns drawing a line between two dots. Draw the last line of a shape and it's yours, and you go again. Most points wins. Pinch to zoom, and drag from one dot to the next to draw.
Hunt: every colour zone hides one bug. No two bugs share a row or column, and none touch, even diagonally. Use the hints if you are stuck.
Sort Lab: three sorting puzzles: pour coloured liquid between tubes, tip trucks onto a ring road at the right moment, and slide blocks to free the ferret. Beat par for three stars.
Bug Lanes: bugs crawl along five lanes toward your core; spend energy on defenders to stop them. Seventy levels, with a boss every eighth level.
Whispers of Wonderland (beta): read the numbers to dispel the fog safely and reach the exit of each floor.
Spark Clicker: tap for sparks, buy generators, and solve locks to trigger surges. It keeps earning while you are away.

Daily puzzles and streaks
Most games have a daily puzzle that is the same for everyone that day. Playing every day builds a streak that counts across all of the games, and longer streaks earn Gems.
Lives
Some games use lives. Your lives are shared across games, refill slowly over time, and can be gifted by guild mates.
Gems
Gems are earned by playing: daily play, achievements and streaks. If you would like to move faster you can also top up on the Get Gems page; bought and earned Gems are identical, and nothing requires a purchase. You can spend Gems on the Shop (VIP, keys, hint packs and themes, though Remove Ads is cash only) and on guild features such as founding a guild.
Guilds
Open your profile and choose the Guild tab to join one with an invite code, browse open guilds, or start your own. Members can ask for lives and help each other. Please keep names and messages friendly; offensive guilds can be reported.
Ads, VIP and Remove Ads
Free players see ads. Optional rewarded ads give a small bonus only if you choose to watch. Buying Remove Ads hides banner ads on every Lock & Spark site for good, and VIP membership (30 days, not automatically renewed) removes ads and adds extra perks. Nothing in the games is locked behind a purchase.
